FAP 蛋白, Human (Biotinylated, HEK293, His-Avi)

The FAP protein is a cell surface glycoprotein serine protease that is critical for extracellular matrix degradation and plays multiple roles in tissue remodeling, fibrosis, wound healing, inflammation, and tumor growth. FAP Protein, Human (Biotinylated, HEK293, His-Avi) is the recombinant human-derived FAP protein, expressed by HEK293 , with N-His, N-Avi labeled tag. The total length of FAP Protein, Human (Biotinylated, HEK293, His-Avi) is 735 a.a., with molecular weight of 90-100 kDa.

FAP 蛋白是一种细胞表面糖蛋白丝氨酸蛋白酶，在细胞外基质降解中起着至关重要的作用，并参与多种细胞过程，包括组织重塑、纤维化、伤口愈合、炎症和肿瘤生长。FAP 的质膜和可溶形式均表现出脯氨酸后裂解内肽酶活性，表明对底物（如 α-2-抗纤溶酶 SERPINF2 和 SPRY2）上的 Ala/Ser-Gly-Pro-Ser/Asn/Ala 共有序列有偏好。FAP 可以降解明胶、热变性 I 型胶原蛋白和各种其他底物。此外，它还具有二肽基肽酶活性，可优先水解合成二肽底物中的脯氨酰键，并优先选择特定氨基酸序列。与 DPP4、PLAUR 或整合素相关，FAP 的质膜形式参与细胞外基质的细胞周蛋白水解，促进细胞粘附、迁移和侵袭。FAP 的多方面功能延伸至发育和伤口愈合过程中的组织重塑。在恶性黑色素瘤中，FAP 增强细胞对细胞外基质的侵袭性，并通过降解蛋白多糖短聚糖促进神经胶质瘤细胞侵入脑实质。FAP 通过增加血管生成、胶原纤维降解和细胞凋亡来促进肿瘤生长进展，但矛盾的是，FAP 通过以丝氨酸蛋白酶活性独立的方式调节细胞增殖和存活，在黑素细胞中充当肿瘤抑制因子。

90-100 kDa

Greater than 95% as determined by Tris-Bis PAGE.

无菌粉末.

Lyophilized from a 0.22 μm filtered solution in 20 mM Tirs, 150 mM NaCl, 200 mM L-Arginine, pH 8.2. Normally 8% trehalose is added as protectant before lyophilization.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O.

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
