Species : Human
Source : HEK293
Tag : His
Protein Length : 176-687 a.a.
Description : B-cell receptor CD22 is also known as Sialic acid-binding Ig-like lectin 2 (Siglec-2), B-lymphocyte cell adhesion molecule (BL-CAM), T-cell surface antigen Leu-14, which belongs to the immunoglobulin superfamily and SIGLEC (sialic acid binding Ig-like lectin) family. CD22 mediates B-cell B-cell interactions, and may be involved in the localization of B-cells in lymphoid tissues. Siglec-2/CD22 binds sialylated glycoproteins, one of which is CD45. Siglec2/CD22 plays a role in positive regulation through interaction with Src family tyrosine kinases and may also act as an inhibitory receptor by recruiting cytoplasmic phosphatases via their SH2 domains that block signal transduction through dephosphorylation of signaling molecules.
Form : Lyophilized
Bio-activity : Immobilized Human CD22 Protein, His-tagged at 2 μg/mL (100 μL/well) can bind Anti-Human CD22 MAb, Human IgG1 with a linear range of 0.1-2 ng/mL (QC tested).
Molecular Mass : The protein has a calculated MW of 57.8 kDa. The protein migrates as 90-100 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Endotoxin : < 1.0 EU/ μg by the LAL method.
Purity : > 95 % as determined by SDS-PAGE
Characteristic : Disulfide-linked homodimer
Labeled with Alexa Fluor 488 via amines
Excitation Wavelength: 488 nm
Emission Wavelength: 515­-545 nm
Storage : For long term storage, the product should be stored at lyophilized state at -20 centigrade or lower.
Storage Buffer : Lyophilized from 0.22 μm filtered solution in PBS, pH7.4.
