Technical Data


Recombinant protein


Total 140 AA. MW: 15.8 kDa (calculated). UniProtKB acc.no. P14555. N-Terminal His-tag, 16 extra AA.

Amino Acid Sequence



E. coli


˃ 90 % by SDS-PAGE


12% SDS-PAGE separation of Human sPLA2-IIA
1. M.W. marker – 14, 21, 31, 45, 66, 97 kDa
2. reduced and heated sample, 10μg/lane
3. non-reduced and non-heated sample, 10μg/lane


< 1.0 EU/µg


Filtered (0,4 μm) and lyophilized in 0.5 mg/mL in 0.05M Acetate buffer pH4


Add 0.1M Acetate buffer pH4 to prepare a working stock solution of approximately 0.5 mg/mL and let the lyophilized pellet dissolve completely. For conversion into higher pH value, we recommend intensive dilution by relevant buffer to a concentration of 10μg/mL. In higher concentrations the solubility of this antigen is limited.


Western blotting


At ambient temperature. Upon receipt, store the product at the temperature recommended below.


Store the lyophilized protein at -80 °C. Lyophilized protein remains stable until the expiry date when stored at -80 °C. Aliquot reconstituted protein to avoid repeated freezing/thawing cycles and store at -80 °C for long term storage. Reconstituted protein can be stored at 4 °C for a week.

Quality Control Test

BCA to determine quantity of the protein.
SDS PAGE to determine purity of the protein. Endotoxin level determination.


This product is intended for research use only.
