Annexin A7/ANXA7 蛋白, Human

Annexin A7 Protein, Human is a 51 kDa multifunctional protein which belongs to the the group A annexin family and contains an extraordinarily long amino terminus. Annexin A7 is a membrane binding protein with diverse properties including voltage sensitive calcium channel activity, ion selectivity and membrane fusion^[1][2].

膜联蛋白由一个蛋白质家族组成，参与细胞膜动力学的许多方面和膜相关蛋白的调节。
膜联蛋白 A7 由 ANXA7 基因编码，是第一个分离的膜联蛋白，介导 Ca ²⁺-调节嗜铬颗粒胞吐作用。膜联蛋白 7 的分子量约为 51 kDa，具有独特的、高度疏水的 N 端结构域（含 167 个氨基酸）和保守的 C 端区域（含 299 个氨基酸）。膜联蛋白 A7 在胞吐过程中的膜融合中发挥着重要作用，主要定位于细胞质中，并且在大脑、心脏和骨骼肌中表现出较高的患病率^[1]。

Immobilized Human Annexin A7 Protein at 5 μg/mL (100 μL/well) can bind Anti-Annexin A7 antibody. The ED₅₀ for this effect is 3.01 ng/mL.

无菌粉末

Lyophilized from a 0.22 μm filtered solution of 10 mM Tris-HCl, 100 mM NaCl, pH 8.0 or 10 mM Tris-HCl, 100 mM NaCl, pH 8.0, 8% trehalose.
Note: For SPR assay, please replace the buffer. Primary amine components (e.g., Tris, imidazole) can affect protein-coupled chips.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years from date of receipt. 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.
