The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Purity70 - 90% by HPLC.
- First try to dissolve a small amount of peptide in either water or buffer. The more charged residues on a peptide, the more soluble it is in aqueous solutions. - If the peptide doesn’t dissolve try an organic solvent e.g. DMSO, then dilute using water or buffer. - Consider that any solvent used must be compatible with your assay. If a peptide does not dissolve and you need to recover it, lyophilise to remove the solvent. - Gentle warming and sonication can effectively aid peptide solubilisation. If the solution is cloudy or has gelled the peptide may be in suspension rather than solubilised. - Peptides containing cysteine are easily oxidised, so should be prepared in solution just prior to use.

Calcium dependent phospholipid binding protein
Cytosolic phospholipase A2
Cytosolic phospholipase A2 group IVA
Phosphatidylcholine 2 acylhydrolase
Phospholipase A2 group 4 A
Phospholipase A2 group IVA
Phospholipase A2 group IVA (cytosolic calcium dependent)
FunctionSelectively hydrolyzes arachidonyl phospholipids in the sn-2 position releasing arachidonic acid. Together with its lysophospholipid activity, it is implicated in the initiation of the inflammatory response.
Tissue specificityExpressed in various tissues such as macrophages, platelets, neutrophils, fibroblasts and lung endothelium.
DomainThe N-terminal C2 domain associates with lipid membranes upon calcium binding. It modulates enzyme activity by presenting the active site to its substrate in response to elevations of cytosolic Ca(2+).
Post-translational modificationsActivated by phosphorylation at both Ser-505 and Ser-727.
Cellular localizationCytoplasm. Cytoplasmic vesicle. Translocates to membrane vesicles in a calcium-dependent fashion.
