Human SIRP Beta/CD172b Protein

产品信息(Product Info)

Recombinant Human SIRP Beta/CD172b Protein is expressed from Expi293 with His tag and Avi tag at the C-terminal. It contains Glu30-Ala369.[Accession | O00241-1]

分子量大小(Molecular Weight)

The protein has a predicted MW of 40 kDa. Due to glycosylation, the protein migrates to 52-60 kDa based on Tris-Bis PAGE result.


Less than 1EU per μg by the LAL method.


> 95% as determined by Tris-Bis PAGE
> 95% as determined by HPLC


Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization.


Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.


-20 to -80°C for 12 months as supplied from date of receipt.
-20 to -80°C for 3-6 months in unopened state after reconstitution.
2-8°C for 2-7 days after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please avoid freeze-thaw cycles.

产品数据(Assay Data)
Tris-Bis PAGE

Human SIRP Beta on Tris-Bis PAGE under reduced conditions. The purity is greater than 95%.


The purity of Human SIRP Beta is greater than 95% as determined by SEC-HPLC.


SIRP beta 1 is a type I transmembrane protein belonging to the SIRP family within the Ig superfamily. Members of this family are characterized by an extracellular region containing a V-set Ig domain containing a J-like sequence and two C1-set Ig domains.SIRP beta 1 is immunoglobulin-like cell surface receptor involved in the negative regulation of receptor tyrosine kinase-coupled signaling processes. Participates also in the recruitment of tyrosine kinase SYK. Triggers activation of myeloid cells when associated with TYROBP.
