Human FAP Protein

Product Info

Recombinant Human FAP Protein is expressed from Expi293 with His tag at the N-terminal. It contains Leu26-Asp760.[Accession | Q12884]

Molecular Weight

The protein has a predicted MW of 86.1 kDa. Due to glycosylation, the protein migrates to 90-100 kDa based on Tris-Bis PAGE result.


Less than 1EU per μg by the LAL method.


> 95% as determined by Tris-Bis PAGE
> 95% as determined by SEC-HPLC


Lyophilized from 0.22μm filtered solution in 20mM Tris, 250mM NaCl (pH 8.2). Normally 5 % trehalose is added as protectant before lyophilization.


Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.


The product should be stored at -70℃ or -20℃.

Assay Data

Fibroblast activation protein (FAP) is a serine protease that has been reported in fibroblasts and some carcinoma cells, which correlates with poor patient outcomes. FAP can be induced under hypoxia which is also vital in the malignant behaviors of cancer cells.
