| Description | In normal adult serum, the approximate percentage composition of IgG with respect to its subclasses is IgG1:65%, Ig2:23%, IgG3:6%, and IgG4:6%. Abnormal levels of one or more subclasses may be associated with autoimmune, anaphylatic and gut diseases, as well as with recurrent infection.Prepared fromIn normal adult serum, the approximate percentage composition of IgG with respect to its subclasses is IgG1:65%, Ig2:23%, IgG3:6%, and IgG4:6%. Abnormal levels of one or more subclasses may be associated with autoimmune, anaphylatic and gut diseases, as well as with recurrent infection.Prepared from myeloma plasma shown to be non reactive for HBsAg, anti-HCV, anti-HBc, and negative for anti-HIV 1 & 2 by FDA-required tests...

Involved in calcium interactions and contractile properties of the cell that may contribute to replicative senescence | Trypsin is a member of the serine protease family. Trypsin cleaves peptides on the C-terminal end of lysine and arginine amino acid residues. The pH optimum of trypsin is pH 7 - 10. The enzyme is inhibited by serine protease inhibitors, e.g. PMSF, and by metal chelating agents, e.g., EDTA. Trypsin is a member of the serine protease family.

The enzyme is inhibited by serine protease inhibitors, e.g. PMSF, and by metal chelating agents, e.g., EDTA. Recombinant Human Trypsin is a genetically engineered protein expressed in E.coli and purified by high pressure liquid chromatography. There are no contaminating enzyme activities such as carboxypeptidase A and chymotrypsin. No protease inhibitors such as PMSF are contained in the preparation.Animal origin free:The use of recombinant Human Trypsin eliminates the risk of virus presence, and of any other potential adventitious agents found in animal pancreas-derived trypsin. Recombinant human trypsin:The amino acid sequence is the same as the Human Trypsin 2.Stable:A sterile recombinant human trypsin lyophilized eliminates the contamination risks and decreases the chance of activity loss in the process of transport and storage.High purity:(1) Recombinant human trypsin provides increased specificity and eliminates contaminating activities found in lower purity enzymes.(2) No other contaminating proteases such as chymotrypsin or carboxypeptidase A...
