种属	Human
表达系统	HEK293 Cells
标签	C-His
蛋白编号	Q16790
别名	MN,Carbonic Anhydrase IX,CAIX,CA9,CA 9
蛋白构建	A DNA sequence encoding the human carbonic anhydrase IX (CA9) (NP_001207.2) (Met1-Asp414) was expressed with a polyhistidine tag at the C-terminus. Predicted N terminal: Gln 38
蛋白纯度	≥ 90 % as determined by SDS-PAGE. ≥ 90 % as determined by SEC-HPLC.
分子量	42.5 kDa (predicted); 49.1 kDa (reducing condition, due to glycosylation)
内毒素	< 1.0 EU/μg of the protein as determined by the LAL method.
缓冲液	Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS, pH 7.4. Typically, a mixture containing 5% to 8% trehalose, mannitol, and 0.01% Tween 80 is incorporated as a protective agent before lyophilization.
复溶方法	A Certificate of Analysis (CoA) containing reconstitution instructions is included with the products. Please refer to the CoA for detailed information.
存储	It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
运输方式	In general, Lyophilized powders are shipping with blue ice.
研究背景	Carbonic anhydrases IX (CA IX), also known as membrane antigen MN or CA9, is a member of the carbonic anhydrase (CA) family and may be involved in cell proliferation and cellular transformation. CAs are zinc metalloenzymes that catalyze the reversible hydration of carbon dioxide (H2O + CO2 = H+ + HCO3–) and thus participate in a variety of biological and physical processes. CA IX protein is expressed primarily in carcinoma cells lines, and the expression is cell density dependent and has been shown to be strongly induced by hypoxia, accordingly facilitates adaptation of tumor cells to hypoxic conditions. It is involved in tumorigenesis through many pathways, such as pH regulation and cell adhesion control. CA IX is used as a marker of tumor hypoxia and as a new therapeutic target for many human carcinomas and cancers.Cancer ImmunotherapyImmune CheckpointImmunotherapyTargeted Therapy
