62 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 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.

64 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.

These are acidic/basic exchange resins consisting of different polymers and copolymers. The particle size of these resins is between mesh and are excellent for cross-linking. Typical application of these resins are for water conditioning, softening and deionionisation, removal of recovery of high molecular weight anions, fractional separation of organic acids, amino acids, metals, peptides, inorganic and rare earth metals. They can also be used for th treatment of sugar solutions, amino acids and enzymes. SRL Ion exchange resins are highly recommended products for critical separation work.

218 BioLit DNA & Protein Tools Our BioLit products range encompasses an assortment of DNA, protein markers & ladders; a variety of Taq polymerases; cloning vectors; an array of buffers, reagents & solutions; tools for DNA & protein purifications; and a medley of educational teaching kits. All these products are designed to be highly pure, precise, ready-to-use and have established a niche for their quality, precision and long-term stability. Over the last few years, we have observed a gradual shift to more Safe and Environmentally Friendly technologies. In view of these industry developments, our team has introduced an entirely new range of offerings and product combinations suit these customer requirements. Some of the revolutionary products in this section of the catalogue are FluroBronze Markers/Ladders Fluorescent DNA ladders & markers These special DNA ladders and marker (RTU) packs contain, in addition to tracking dyes, a non-carcinogenic nucleic acid stain for detection of the ladder bands. This nucleic acid stain (FluroBronze Stain) replaces ethidium bromide (a known potential mutagen if not handled carefully) in agarose gel preparation. 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.
