Source

Human PLA2G1B, His Tag (PLB-H5228) is expressed from human 293 cells (HEK293). It contains AA Ala 23 - Ser 148 (Accession # AAI06726).

Predicted N-terminus: Ala 23

Molecular Characterization

PLA2G1B(Ala 23 - Ser 148)AAI06726
Poly-his

This protein carries a polyhistidine tag at the C-terminus.

The protein has a calculated MW of 15 kDa. The protein migrates as 19 kDa under reducing (R) condition (SDS-PAGE).

Endotoxin

Less than 1.0 EU per μg by the LAL method.

Purity

>95% as determined by SDS-PAGE.

Formulation

Lyophilized from 0.22 μm filtered solution in 50 mM Sodium Acetate, 100 mM NaCl, pH4.5. Normally trehalose is added as protectant before lyophilization.

  1. 4-8°C for 12 months in lyophilized state;
  2. -70°C for 3 months under sterile conditions after reconstitution.
 

SDS-PAGE

Human PLA2G1B, His Tag (Cat. No. PLB-H5228) SDS-PAGE gel

Human PLA2G1B, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.

 

Background

Phosphatidylcholine 2-acylhydrolase 1B (PLA2G1B) is also known as Phospholipase A2 (PLA2), PLA2A, PPLA2, which belongs to the phospholipase A2 family. PLA2G1B is activated by trypsin cleavage in the duodenum and can also be activated by thrombin or autocatalytically. PLA2 catalyzes the calcium-dependent hydrolysis of the 2-acyl groups in 3-sn-phosphoglycerides, this releases glycerophospholipids and arachidonic acid that serve as the precursors of signal molecules.
