CD45 Protein, Human, Recombinant (aa 26-577, hFc)

PTPRC (also known as CD45),T cells require the protein tyrosine phosphatase CD45 to detect and respond to antigen because it activates the Src family kinase Lck, which phosphorylates the T cell antigen receptor (TCR) complex. CD45 ativates Lck by opposing the negative regulatory kinase Csk. Paradoxically, CD45 has also been implicated in suppressing TCR signaling by dephosphorylating the same signaling motifs within the TCR complex upon which Lck acts. CD45 Protein, Human, Recombinant (aa 26-577, hFc) is expressed in HEK293 mammalian cells with C-hFc tag. The predicted molecular weight is 87.53 kDa and the accession number is P08575-3.

产品描述

种属	Human
表达系统	HEK293 Cells
标签	C-hFc
蛋白编号	P08575-3
别名	CD45, CD45R, LCA, PTPRC, L-CA, T200, B220, GP180, LY5, EC 3.1.3.48
蛋白构建	Gln26-Lys577
蛋白纯度	> 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC
分子量	87.53 kDa (predicted). Due to glycosylation, the protein migrates to 120-160 kDa based on Tris-Bis PAGE result.

内毒素	< 1 EU/μg by the LAL method.
缓冲液	Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS (pH 7.4). Typically, 8% trehalose is incorporated as a protective agent before lyophilization.
复溶方法	Reconstitute the lyophilized protein in distilled water. The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing.
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℃. For reconstituted proteinsolutions, 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.
