产品信息

生物活性	Activity testing is in progress. It is theoretically active, but we cannot guarantee it. If you require protein activity, we recommend choosing the eukaryotic expression version first.
产品描述	CEACAM5 Protein, Human, Recombinant (His), Biotinylated is expressed in HEK293 mammalian cells with His tag. The predicted molecular weight is 72.8 kDa and the accession number is A0A024R0K5.
种属	Human
表达系统	HEK293 Cells
标签	C-His
蛋白编号	P06731
别名	CEA,CD66e,carcinoembryonic antigen-related cell adhesion molecule 5
蛋白构建	A DNA sequence encoding the mature form of human CEACAM5 (NP_004354.2) (Met1-Ala685) was fused with a polyhistidine tag at the C-terminus. The purified protein was biotinylated in vitro. Predicted N terminal: Lys 35
蛋白纯度	> 95 % as determined by SDS-PAGE.
分子量	72.8 kDa (predicted); 100-110 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	CEACAM5, also known as CEA or D66e, belongs to the large CEACAM subfamily of the immunoglobulin superfamily. CEACAM5 is expressed primarily by epithelial cells, and is synthesized as a glycoprotein with an MW of 180 kDa comprising 60% carbohydrate. CEACAM5 contains one Ig-like V-type domain at the N-terminus, followed by six Ig-like C2-type domains and a GPI anchor, and exists as a homodimer. CEACAM5 and CEACAM6 are overexpressed in many cancers and are associated with adhesion and invasion. CEACAM5 can mediate cell-cell adhesion through homotypic and heterotypic interactions. It functions as a homotypic intercellular adhesion molecule and serves as a widely used tumor marker, since it is expressed at higher levels in tumorous tissues than in corresponding normal tissues. CEACAM5 has also been shown to contribute to tumorigenicity by inhibiting cellular differentiation. In addition, CEACAM5 is identified as the host receptor for the Dr family of adhesins of E.Coli, and the binding of E.coli Dr adhesins leads to dissociation of the CEACAM5 homodimer.Cancer ImmunotherapyImmune CheckpointImmunotherapyTargeted Therapy
