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 linking and cross-linking reagents are important reagents with highly purified production processes and are used typically in protein chemistry applications. Commonly used to modify nucleic acids, drugs and solid surfaces, bio-conjugation, immobilization, bio-molecule labeling, identification of nearneighbor protein relationships and for studying ligand-receptor interactions. 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. 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 indispensable to biochemists and molecular biologists. Gel Filtration is extensively 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.

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.

code product name application/description unit unit price old/new ` BioLit Ready-to-use Protein Molecular Weight Standards BioLit protein molecular weight standards cover the useful range of protein sizes that a researcher or student requires for routine experiments. The recommended loading volume is 20 μl, giving approximately 5 μg of each protein sufficient for detection by Coomassie blue staining. The products are unstained markers. The proteins have been dissolved and denatured in the standard SDS-PAGE sample-loading buffer. Prepared under sterile conditions, these markers have appropriate additives to ensure long-term stability when they are stored in a refrigerator or freezer and even with brief exposure to room temperature. Although boiling is not required prior to loading, doing so will not affect results.
