  1Measured by its binding ability in a functional ELISA.Immobilized Human SIRPB1 at 2 μg/mL can bind anti-SIRPB1 recombinant antibody (CSB-RA021335MA1HU) .The EC50 is 0.9675-1.114 ng/mL. 2SIRPB1 Recombinant Monoclonal Antibody (CSB-RA021335MA1HU) captured on Protein A Chip can bind Human SIRPB1 with an affinity constant of 0.245 nM as detected by MetaSPR Assay (WeSPRTM 200) .

• Form:

  Lyophilized powder

• Buffer:

  Lyophilized from a 0.2 μm sterile filtered PBS, 6% Trehalose, pH 7.4

• Reconstitution:

  We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
