Based on the high binding affinity between biotin-streptavidin systems, our Streptavidin series products are recommended to use together with biotinylated proteins to get lower non-specific binding results in a shorter time.
This protein carries a human IgG1 Fc tag at the C-terminus, followed by an Avi tag (Avitag™).
The protein has a calculated MW of 65.8 kDa. The protein migrates as 75-105 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
>95% as determined by SDS-PAGE.
>90% as determined by SEC-MALS.
Supplied as 0.2 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5 with trehalose as protectant.

Biotinylated Human SIRP alpha, Fc,Avitag on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 95%.
The purity of Biotinylated Human SIRP alpha, Fc,Avitag (Cat. No. CDA-H82F2) is more than 90% and the molecular weight of this protein is around 155-170 kDa verified by SEC-MALS.
FACS assay shows that Biotinylated Human SIRP alpha, Fc,Avitag (Cat. No. CDA-H82F2) can bind to Jurkat cell expressing CD47. The concentration of SIRP alpha used is 3 μg/mL (QC tested).
FACS analysis shows that the binding of Biotinylated Human SIRP alpha, Fc,Avitag (Cat. No. CDA-H82F2) to Jurkat expressing CD47 was inhibited by increasing concentration of neutralizing Anti- Human CD47 antibody. The concentration of SIRP alpha used is 1 μg/mL. IC50=0.1303 μg/mL (Routinely tested).

ComboX is a new brand of ACROBiosystems. ComboX products include our Streptavidin series products, coated plates, isotype controls for antibody and fusion protein drug research, and general-purpose antibodies.
To enable antibody characterization methods, ACROBiosystems has developed a series of enzymes, such as IdeS, SpeB, EndoH, and Endo S proteases, to assist with the characterization of antibodies and their related post-translational modifications (PTMs).
ACROBiosystems developed a series of GMP grade cytokines under the GMP grade quality management system. Those products are all suitable for T/NK cell generation, activation, and proliferation in cell therapy research.
50+ targets designed for CAR detection, including PE/FITC/biotin labeled proteins. The key reagents for CD19 and BCMA were FDA DMF filed which can support your IND, NDA and BLA process.
GMP grade cytokines, reagents for cell activation, gene edition, DNA/RNA removal, etc. Particularly focus on product design, quality control and solution-based support to link each phase of your cell and gene therapy journey.
Full length multi-pass TPs with stabilized structure and high bioactivity for immunization, antibody screening, cell based assay and CAR detection, including hot CD20, Claudin 18.2， CD133, GPRC5D，CCR8, CCR5, etc.
CD3 proteins and a collection of for bispecific antibody development which are of high specificity and bioactivities and suitable for immunization, antibody screening.
A series of immune checkpoints including classic co-inhibitory and co-stimulatory receptors. The comprehensive catalog contains 100+ targets with various species and tags, and the high-quality proteins are in good batch-to-batch consistency.
To meet the needs of ADCs development, ACROBiosystems can provide: A variety of high-quality target proteins; MMPs/Cathepsin/uPA for cleavable linker; Anti-payload antibodies & anti-idiotypic antibodies for immunogenicity and PK analysis; SPR/BLI analytical and ADA development service.
