The complement system provides innate defense against microbial infection and is a "complement" to antibody mediated immunity. The complement system consists of thirty-five interacting plasma and membrane associated proteins which contribute to host-defense and initiate and amplify inflammation, even in the preimmune state where specific antibodies and lymphocytes are not available. In addition to the complement components themselves, this system also contains several soluble factors that prevent spontaneous complement activation from occurring in solution, as well as, several regulatory membrane associated proteins that protect host cells from accidental complement attack. Cleavage of the C3 component by either the classical pathway or the alternative pathway releases C3a and C3b. C3a appears to be important in many inflammatory responses while the C3b fragment covalently binds to the cell or bacterial surface and plays a role in opsonisation. Binding of C3b to the C4b component of the C3 convertase, results in C5 convertase (C4b3b2a) formation.

The total protein is measured using the Biuret procedure with bovine albumin as the standard; F/P ratio is calculated using absorbance at 491.5nm. Antibody titer of the IgG fraction is standardized with an in-house control by immunoelectrophoresis. The IgG fraction is tested for purity and specificity at 40 mg/mL using immunoelectrophoresis; No trace of albumin is detected. Antibody activity to serum albumin is not present.

SPINeasy® DNA Kit for Tissue (with Lysing Matrix) is a high-performance genomic DNA (gDNA) extraction kit which combines mechanical, chemical and enzymatic disruption of tissue samples in 30 minutes. The addition of proteinase K allows a more efficient and complete digestion of any tissue type. Homogenizing time is greatly reduced while substantially increasing the gDNA yield and purity. The kit is validated for tissue samples of fatty, tough, and fibrous samples, and suitable for downstream applications such as PCR and qPCR.

Daunosamine hydrochloride

Supplier: MP Biomedicals

Heparin is a polymer classified as a mucopolysaccharide or a glycosoaminoglycan. It is biosynthesized and stored in mast cells of various mammalian tissues, particularly liver, lung and mucosa. It is made up of repeated disaccharide units consisting of 1,4-linked L-iduronic acid and D-glucosamine. The iduronic acid residues are O-sulfated at position 2, and the glucosamine residues are N-sulfated and O-sulfated at position 6. The repeated block can be interrupted or extended by residues of beta-D-glucuronic acid and 6-O-sulfated N-acetyl-alpha-D-glucosamine.
