Proteins & Enzymes
Streptavidin (from Streptomyces avidinii) is conjugated with highly purified alkaline phosphatase (calf intestine) by a modified glutaraldehyde method. The typical working dilution is 1:500-1:1250 for immunoblotting, 1:1000-1:12500 for ELISA, and 1:20-1:50 for immunohistochemistry. 2 ml.
Bovine Albumin 30% Solution Polymer Enhanced
30% Polymer Enhanced Solution
Prepared from high quality Fraction V Powder intended for in vitro diagnostic use in immunohematological procedures requiring high protein diluent. It can be used for serological procedures, and it potentiates the expression of weak antigen-antibody reactions and avidity of red blood cells.
Cellulase Y-C (From Trichoderma Viride)
Cellulase Y-C enzyme retains very high filter paper decomposing activity and showed an appreciable amount of hemicellulase. Actually, this enzyme removed cell walls from plant tissues in shorter incubation period without loss of biological activity of the materials.
Proline Specific Endopeptidase (From Flavobacterium Meningosepticum)
Proline Specific Endopeptidase specifically cleaves peptide bonds on the carboxy side of proline residues. Much slower hydrolysis is observed on the carboxy side of alanine residues. This enzyme is very close, in its properties, to a post-proline cleaving enzyme. The substrates have been found to have the general structure Y-Pro-X, where Y is a peptide or N-protected amino acid and X may be an amino acid, peptide, amide or ester.
Tryptase (Purified Antigen)
Tryptase is a glycoprotein released from mast cells during anaphylaxis, which performs a number of functions including catalyzing the activation of complement C3, converting prostromelysin to stromelysin (MMP-3), and cleaving fibrinogen resulting in a loss of clotting potential. Human tryptase is a major secretory protease of human lung mast cells.
