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

Catalog No. TMPK-00447 Copy Product Info

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.

Biological Activity	Immobilized AHuman CD45, hFc Tag at 0.5 μg/mL (100 μL/well) on the plate. Dose response curve for Biotinylated Anti-CD45 Antibody, hFc Tag with the EC50 of 0.16 μg/mL determined by ELISA.
Description	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.

Species	Human
Expression System	HEK293 Cells
Tag	C-hFc
Accession Number	P08575-3
Synonyms	T200,PTPRC,LY5,L-CA,LCA,GP180,EC 3.1.3.48,CD45R,CD45,B220
Construction	Gln26-Lys577
Protein Purity	> 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC
Molecular Weight	87.53 kDa (predicted). Due to glycosylation, the protein migrates to 120-160 kDa based on Tris-Bis PAGE result.
Endotoxin	< 1.0 EU/μg of the protein as determined by the LAL method.
Formulation	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.
Reconstitution	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.
Stability & Storage	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.
Shipping	In general, lyophilized powders are shipped with blue ice, while solutions are shipped with dry ice.
