Source :
Human SIRP beta, Fc Tag (SIA-H5257) is expressed from human 293 cells (HEK293). It contains AA Glu 30 - Leu 371 (Accession # O00241-1).
Endotoxin :
Less than 1.0 EU per μg by the LAL method.
Purity :
>90% as determined by SDS-PAGE.
SDS-PAGE Remark(R&NR) :
Human SIRP beta, Fc Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 90%.
Formulation :
Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization. Contact us for customized product form or formulation.
Reconstitution :
Please see Certificate of Analysis for specific instructions. For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.
Storage :
For long term storage, the product should be stored at lyophilized state at -20°C or lower. Please avoid repeated freeze-thaw cycles. This product is stable after storage at:
● -20°C to -70°C for 12 months in lyophilized state;
● -70℃ for 3 months under sterile conditions after reconstitution.
Background :
Signal-regulatory protein beta-1 (SIRP beta 1) also known as SIRPβ1, belongs to signal-regulatory-protein (SIRP) family, and immunoglobulin superfamily. SIRPβ1 is a transmembrane protein that has three Ig-like domains in its extracellular region and a short cytoplasmic tail. Human SIRPβ1 is expressed on monocytes and granulocytes but not on lymphocytes. SIRP beta 1 contains short cytoplasmic domains that lack cytoplasmic sequence motifs capable of recruiting SHP-2 and SHP-1. In addition, they contain a single basic lysine residue within the hydrophobic transmembrane domain.

company information
ACROBiosystems
ACROBiosystems is a leading manufacturer of recombinant proteins and other critical reagents to support the development of target therapeutics, vaccines and diagnostic kits.
Our team has worked tirelessly since the genomic sequence of SARS-CoV-2 was first published, developing a serial of critical reagents to fight COVID-19. Our team has successfully developed a new neutralizing antibody titer serologic assay kit for COVID-19 vaccine evaluation (Cat.No.TAS-K022) which really showed excellent performance.
As the emerging variants may have impacted on the development of the COVID-19 epidemic, our team is also going full steam ahead on developing a collection of spike mutants for the emerging variants of SARS-COV-2. The reagents can be used to evaluate the efficacy of the antibodies and vaccination.
We have also developed an extensive collection of recombinant proteins to support the development for bispecific antibodies, antibody drug conjugates and cell therapies.
