Recombinant Phospholipase A2 P

Phospholipase A2, Phosphatidylcholine 2-acylhydrolase, Allergen Api m I, Api m 1.

Bee venom phospholipase A2 (PLA) is the main allergen in the bee sting allergy. Bee venom phospholipase A2 (BV-PLA2) is a hydrolytic enzyme which specifically cleaves the sn-2 acyl bond of phospholipids at the lipid/water interface. BV-PLA2 is a 14–16-kDa glycoprotein, consisting of 134 amino acids and displaying a single carbohydrate side chain at the residue Asn13. It is also held to be responsible for some systemic anaphylactic reactions in bee venom sensitized individuals. BV-PLA2 presents 3 peptide and a glycopeptide T cell epitopes, which are recognized by both allergic and non-allergic bee venom sensitized subjects. PLA is able to elicit both IgE mediated allergy and normal immunity to bee sting which usually is associated with high affinity IgG4 anti-PLA antibodies.

The E.Coli derived recombinant protein contains phospholipase P00630 bee venom protein epitopes, 26-162 amino acids. Phospholipase A2 P00630 Bee Venom is fused to a 6xHis tag at C-terminus

Escherichia Coli.

Purified by proprietary chromatographic technique.

Protein is >90% pure as determined by 10% SDS-PAGE.

1XPBS pH 7.2 and 50% glycerol.

Phospholipase A2 although stable at 4°C for 1 week, should be stored below -18°C. 
Please prevent freeze thaw cycles.
