Human SIRP Beta 1 isoform 3 Protein
Recombinant Human SIRP Beta 1 isoform 3 Proteinis expressed from HEK293 with His tag and Avi tag at the C-Terminus.It contains Glu30-Leu371 [Accession | Q5TFQ8-1].
The protein has a predicted MW of 39.9 kDa. Due to glycosylation, the protein migrates to 60-70 kDa based on Bis-Tris PAGE result.
> 95% as determined by Bis-Tris PAGE
> 95% as determined by HPLC
Less than 1EU per μg by the LAL method.
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Centrifuge the tube 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.
-80°C for 3 months after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Human SIRP Beta 1 isoform 3 on Bis-Tris PAGE under reduced condition. The purity is greater than 95%.
The purity of Human SIRP Beta 1 isoform 3 is greater than 95% as determined by SEC-HPLC.
Signal regulatory protein β1 (SIRPB1) is a signal regulatory protein member of the immunoglobulin superfamily and is capable of modulating receptor tyrosine kinase-coupled signaling. Copy number variations at the SIRPB1 locus were previously reported to associate with prostate cancer aggressiveness in patients.SIRPB1 gene amplification and overexpression were detected in prostate cancer specimens. The knockdown of SIRPB1 significantly suppressed cell growth in colony formation assays and cell mobility.
