Recombinant Human CD79B Protein, hFc-tagged, Alexa Fluor 647 conjugated

Specification :
| Description : B-cell antigen receptor complex-associated protein beta chain (CD79b) is also known as B-cell-specific glycoprotein B29, Ig-beta,Immunoglobulin-associated B29 protein, B29 and IGB, which is a single-pass type I membrane protein containing one Ig-like V-type (immunoglobulin-like) domain and one ITAM domain.CD79b is required in cooperation with CD79A for initiation of the signal transduction cascade activated by the B-cell antigen receptor complex (BCR).CD79b can enhance phosphorylation of CD79A, possibly by recruiting kinases which phosphorylate CD79A or by recruiting proteins which bind to CD79A and protect it from dephosphorylation. Defects in CD79b are the cause of agammaglobulinemia type 6 (AGM6) that is a primary immunodeficiency characterized by profoundly low or absent serum antibodies and low or absent circulating B cells due to an early block of B-cell development. | Source : HEK293 | Species : Human | Tag : hFc | Form : Lyophilized | Molecular Mass : The protein has a calculated MW of 41.8 kDa. The protein migrates as 50-65 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation. | Protein length : 131 | Endotoxin : | Purity : > 92 % as determined by SDS-PAGE | Characteristic : Disulfide-linked homodimerLabeled with Alexa Fluor 647 via aminesExcitation = 650 nmEmission = 668 nm | Storage : For long term storage, the product should be stored at lyophilized state at -20 centigrade or lower.Please avoid repeated freeze-thaw cycles.This product is stable after storage at:-20 to -70 centigrade for 12 months in lyophilized state;-70 centigrade for 3 months under sterile conditions after reconstitution. | Storage Buffer : Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5, 10% trehalose. | Reconstitution : It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 μg/μL. Centrifuge the vial at 4 centigrade before opening to recover the entire contents.
