Biotinylated Human FAP Protein, His-Avi Tag

Description :
FAQ COA 已发表文献 FAP (also known as seprase) is a 95 kDa Type II transmembrane serine protease that is structurally related to dipeptidyl peptidase IV (DPPIV/CD26). Within the extracellular domain (ECD), human FAP shares 90% amino acid (aa) sequence identity with mouse and rat FAP. A soluble and enzymatically active form of FAP known as antiplasmin-cleaving enzyme (APCE) circulates in human plasma. FAP is expressed on reactive stromal fibroblasts in tumor tissue and wound healing and on synoviocytes in rheumatoid arthritis. FAP is also an endopeptidase that can degrade Gelatin, Collagens I and IV, Fibronectin, and Laminin as well as several peptide hormones (e.g. Neuropeptide Y, Brain Natriuretic Peptide, Substance P, Peptide YY, and Incretins). The enzymatic activity is dependent on FAP association with DPPIV on the cell surface. The matrix-dedgrading activity of FAP contributes to tumor cell migration and invasion. In addition, FAP can enhance tumor cell growth by limiting the development of anti-tumor immunity. 产品性质 Synonyms FAP; FAPalpha; SIMP; Seprase; APCE; DPPIV; DPPIVA; FAPA Uniprot No. Q12884 Source Recombinant Biotinylated Human FAP Protein is expressed from HEK293 Cells with His tag and Avi tag at the N-terminal. It contains Leu26-Asp760. Molecular Weight The protein has a predicted MW of 87.9 kDa. Due to glycosylation, the protein migrates to 90-100 kDa based on Tris-Bis PAGE result. Physical Appearance Sterile Filtered White lyophilized (freeze-dried) powder. Purity > 95% as determined by SDS-PAGE and HPLC Endotoxin 1.0EU per 1g of the protein by the LAL method. Formulation Lyophilized from 0.22m filtered solution in 20mM Tirs, 150mM NaCl, 200mM L-Arginine (pH 8.2). Normally 8% trehalose is added as protectant before lyophilization. Reconstitution Centrifuge tubes before opening. Reconstituting to a concentration more than 100g/mLis recommended. Dissolve the lyophilized protein in distilled water.
