CA12/Carbonic Anhydrase 12 蛋白, Human (HEK293, His)

CA12 (or carbonic anhydrase 12) plays a crucial role in the reversible hydration of carbon dioxide, catalyzing its conversion into bicarbonate ions and protons. This enzymatic activity is essential for key physiological processes, including regulating pH and maintaining acid-base balance. CA12/Carbonic Anhydrase 12 Protein, Human (HEK293, His) is the recombinant human-derived CA12/Carbonic Anhydrase 12 protein, expressed by HEK293 , with C-His labeled tag. The total length of CA12/Carbonic Anhydrase 12 Protein, Human (HEK293, His) is 267 a.a., with molecular weight of 40-45 kDa.

CA12 蛋白，也称为碳酸酐酶 12，在二氧化碳的可逆水合中发挥着关键作用。这种酶催化二氧化碳转化为碳酸氢根离子和质子，对基本的生理过程做出了重大贡献。其酶活性对于调节 pH 水平至关重要，有助于维持体内酸碱平衡。作为碳酸酐酶家族的一员，CA12 参与与组织中二氧化碳转运和缓冲相关的基本生化反应，强调了其在细胞稳态中的重要性。

无菌粉末.

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants 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.
