Also, anions of SDS bind to the main peptide chain (at a ratio of one SDS anion for every two amino acid residues) and this effectively imparts a negative charge that is proportional to the mass or molecular weight of that protein 14374 Sodium Lauryl Sulphate 530.00 500g 194821 ExiPlus 4850.00 5000g meets compendial specs of USP, BP, Ph.Eur (Sodium dodecyl sulphate, SDS, SLS) C 12 H 25 SO 4 Na M.W. 288.38 [151-21-3] Assay min.85% 54468 Sodium Lauryl Sulphate 966.00 100g 1948101 extrapure AR, ACS 2050.00 250g (Sodium dodecyl sulphate, SDS, 3980.00 500g SLS) for SDS electrophoresis 7300.00 1kg C 12 H 25 SO 4 Na M.W. 288.38 [151-21-3] Assay(C12)(GC) min.99% 99671 Sodium Lauryl Sulphate 620.00 10g 1942302 for HPLC (ion pairing reagent) 1200.00 25g (Sodium dodecyl sulphate, SDS 3300.00 100g SLS) 16800.00 1kg C 12 H 25 SO 4 Na M.W. 288.38 [151-21-3] Assay(C12)(GC) min.99% 32096 Sodium Lauryl Sulphate 425.00 25g 1944112 for molecular biology 1400.00 100g (Sodium dodecyl sulphate, SDS, 4800.00 500g SLS) 8500.00 1000g DNase, RNase, protease not detected C 12 H 25 SO 4 Na M.W. 288.38 [151-21-3] Assay(C12)(GC) min.99% 35825 Sodium Lauryl Sulphate 690.00 25g 1944318 High Purity 1800.00 100g (Sodium dodecyl sulphate, SDS 8500.00 500g SLS) C 12 H 25 SO 4 Na M.W. 288.38 [151-21-3] Assay(C12)(GC) min.99.5% The high C12 content of this product, 99.5%, is ideally suited for Pharmaceutical Quality Control testing applications, especially for Dissolution Testing. 85369 Sodium Lauryl Sulphate 1300.00 100ml 1924386 10% Solution (10% SDS Solution, SLS) 87547 Sodium Lauryl Sulphate 1800.00 250ml 1924387 20% Solution (20% SDS Solution, SLS) 93117 Sodium Lauryl Suphate IP Discontinued S4P312 (Sodium dodecyl sulphate, SDS, SLS) C 12 H 25 SO 4 Na M.W. 288.38 [151-21-3] Assay min.85% 34378 Sodium Lauryl Sulphate BP 5838.00 1000g S4P313 (Sodium dodecyl sulphate, SDS, SLS) C 12 H 25 SO 4 Na M.W. 288.38 [151-21-3] Assay min.85% 21705 Sodium Metabisulphite 260.00 500g 1949129 extrapure AR Na 2 S 2 O 5 M.W. 190.10 [7681-57-4] Assay min.98% 52693 Sodium Metabisulphite 280.00 500g extrapure AR, ACS, ExiPlus meets compendial specs of USP, BP Na 2 S 2 O 5 M.W. 190.10 [7681-57-4] Assay min.98% 51153 Sodium Metaperiodate 990.00 100g 1947175 pure 4700.00 500g (Sodium periodate) 9200.00 1000g NaIO 4 M.W. 213.89 [7790-28-5] Assay min.99% 23621 Sodium Metaperiodate 1150.00 100g 194934 extrapure AR 4900.00 500g (Sodium periodate) NalO 4 M.W. 213.89 [7790-28-5] Assay min.99.5% 30037 Sodium Metaperiodate 1350.00 100g extrapure AR, ACS, ExiPlus 5150.00 500g (Sodium periodate) meets compendial specs of USP, BP, Ph.Eur NalO 4 M.W. 213.89 [7790-28-5] Assay min.99% 41670 Sodium Methoxide 599.00 500g 194790 Powder pure CH 3 ONa M.W. 54.02 [124-41-4] Assay min.98% 13547 Sodium Molybdate Dihydrate 600.00 100g 1947166 pure 1450.00 250g 2100.00 500g 4100.00 1000g Na 2 MoO 4.2H 2 O M.W. 241.95 [10102-40-6] Assay min.98% 18108 Sodium Molybdate Dihydrate 700.00 100g 1949102 extrapure AR 1550.00 250g 2300.00 500g 4500.00 1kg Na 2 MoO 4.2H 2 O M.W. 241.95 [10102-40-6] Assay min.99% 70851 Sodium Molybdate Dihydrate 800.00 100g extrapure AR, ACS, ExiPlus 1700.00 250g 2600.00 500g 4900.00 1kg meets compendial specs of USP, BP, Ph.Eur Na 2 MoO 4.2H 2 O M.W. 241.95 [10102-40-6] Assay min.99% 72 Storage : 0-4 C 2-8 C -20 C

This is the buffer of choice for several in vitro diagnostic assay reagents & buffer systems for agarose and polyacrylamide gel electrophoresis of proteins and nucleic acids. Tris buffer is preferred to phosphate buffer systems due to very low heavy metal content and protection against preservation of enzyme activity under frozen state during lyophilization. It acts as a stable buffer system in the determination of activity of many enzymes.

Linkers & Cross-Linkers for Protein Chemistry Cross-linking is the process of chemically joining two or more molecules by a covalent bond. SRL introduced linking and cross-linking reagents are important reagents used in protein chemistry applications. Typically, they are commonly used reagents to modify nucleic acids, drugs and solid surfaces. Areas of research where these products find application are bio-conjugation, immobilization, surface modification and bio-molecule labeling. These reagents contain reactive ends to specific functional groups, such as primary amines and sulfhydryls, on proteins or other molecules. The availability of several chemical groups in proteins and peptides make them targets for conjugation and for study using cross-linking methods. Some common applications of cross-linkers is for the identification of near-neighbor protein relationships and for ligand-receptor interactions. 3-(Acetamidomethylthio)propanoic Acid (MPA(Acm)) 3-(Benzylthio)-Propionic Acid DABCYL-N-Succinimidyl Ester DHP Linker (3,4-Dihydro-2H-Pyran-2-Methanol) 5-(Ethylthio)-1H-Tetrazole (ETT) HMBA Linker (4-(Hydroxymethyl)benzoic Acid) HMPA Linker Ramage Linker Rink Amide Linker (Knorr Linker) Sieber Linker Weinreb Linker Compounds for Peptide Synthesis Peptide synthesis is characterized as the formation of a peptide bond between two amino acids. While the definition of a peptide is not definitive, it usually refers to chains of up to 30-50 amino acids. Peptide synthesis today is a common approach in even high-throughput biological research and product and drug development, although it is a technique about 100 years old.

Seraloses TM Media for Gel Filtration and Affinity Chromatography Gel Filtration (Molecular Sieving or Size Exclusion Chromatography) and Affinity Chromatography are rapidly becoming indispensable to biochemists and molecular biologists. Gel Filtration is used for the separation of macromolecules from smaller molecules, for fractionation of mixtures of various biopolymers on the basis of molecular size, for characterizing macromolecules and determining molecular weights and molar masses, for pathological screening of body fluids and for structure determination studies. Affinity Chromatography, besides being put to many of the above uses, is mainly employed for the isolation and purification of biologically active substances like enzymes, antibodies, antigens, lectins, viruses and toxins. Affinity Chromatography has the advantage of being rapid and highly selective.

Restriction Enzymes Common and widely used restriction enzymes in appealing pack sizes, such as HindIII, EcoRI, EcoRV, BamHI, KpnI, PvuII, BglI, SmaI, PstI, EcoRV and DraI. Environmentally friendly Combo packs of DNA ladders & markers These combo packs contain regular or fluorescent ladders/markers accompanied with a special loading buffer which can be used for other nucleic acid samples. Environmentally friendly Stains and dyes We introduced the environmentally friendly SafeDye Stain and observed ecstatic feedback and response from our environmentally aware and health conscious researchers. We are now excited to introduce another stain (FluroBronze Stain) which is mixed, not with the agarose but with nucleic acid samples. This helps in minimizing the mix of stains with the agarose or the buffer and helps us in our stride towards a safer scientific world. Ready-to-use buffers To help students and first-time researchers we bring ready-to-use Gel Mixes for SDS-PAGE analysis. This prevents pipetting errors and minimizes the time in preparation of polyacrylamide gels. BioLit products, with their consistently accurate results in a wide-range pack sizes, are designed to suit research institutes and educational laboratories, moderate and even small labs. Our customers can seek any technical queries, clarifications and guidance from our user-friendly QC and customer service departments. Customization queries for select products are always entertained.

BioLit Ready-to-use DNA Molecular Weight Standards BioLit DNA markers come in many useful ranges to cover most of the requirements of researchers and students. The markers are provided in a ready-to-use format for convenience and high reproducibility. We recommend a volume of 10 µl (~1 µg total DNA) per load to ensure that distinct, prominent DNA bands are observed even with a less sensitive UV transilluminator or in a less than optimal dark chamber. Users might be able to load a volume less than that recommended (without compromising results) if a high-sensitivity gel documentation system is available. The markers have been carefully prepared under sterile conditions and stored in 10 mm Tris-HCl, ph 7.5, 1 mm EDTA and 1 mg/ml sodium azide and are unstained markers. Stocks will be stable for several months if properly stored frozen or even refrigerated. 10344 Low-Range DNA This marker range has been designed 15 µg 2590.00 BLM006 Marker: 0.1 1kb to assist in determining the size of PCR 50 µg 7703.00 product, insert and restriction analysis. 100 µg 14694.00 These ready-to-load DNA markers contain Bromophenol Blue as the tracking dye.
