Description
Signal-regulatory protein beta 1 (SIRP beta 1) is a disulfide-linked type I membrane glycoprotein that belongs to the SIRP/SHPS (CD172) family of the immunoglobulin (Ig) superfamily. Human SIRP beta 1 shares a 57% sequence identity with mouse and rat SIRP beta 1. Formation of the SIRP beta 1/DAP12 complex in myeloid cells induce tyrosine phosphorylation, mitogen-activated protein kinase activation, and cellular activation.

Source |
Recombinant Biotinylated Human SIRP Beta/CD172b Protein is expressed from HEK293 Cells with His tag and Avi tag at the C-terminal. It contains Glu30-Ala369. |
|
Molecular Weight |
The protein has a predicted MW of 40 kDa. Due to glycosylation, the protein migrates to 55-65 kDa based on Tris-Bis PAGE result. |
|
Physical Appearance |
Sterile Filtered White lyophilized (freeze-dried) powder. |
|
Purity |
> 95% as determined by SDS-PAGE and HPLC |
|
Endotoxin |
< 1.0 EU per 1μg of the protein by the LAL method. |
|
Formulation |
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. |
|
Reconstitution |
Centrifuge tubes before opening. Reconstituting to a concentration more than 100μg/mL is recommended. Dissolve the lyophilized protein in distilled water. |
Storage
The products are shipped with ice pack and can be stored at -20℃ for 1 year.
2-7 days, 2 to 8 °C under sterile conditions after reconstitution.
3 -6 months, -20 to -80°C under sterile conditions after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please avoid freeze-thaw cycles.
