Active Recombinant Human SIRPA protein, His-Avi-tagged, Biotinylated

• Cat.No.: SIRPA-0686H
• Product Overview: Biotinylated Recombinant Human SIRPA protein(Glu31-Arg369), fused with His and Avi tag, was expressed in HEK293.

Specification

• Species: Human
• Source: HEK293
• Tag: Avi&His
• Protein Length: 31-369 a.a.
• Form: Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.
• Bio-activity: Immobilized Human CD47, Fc Tag (HPLC-verified) at 2 μg/mL (100 μL/well) can bind Biotinylated Human SIRP alphaV2, His,Avitag with a linear range of 0.039-0.625 μg/mL.
• Molecular Mass: This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag).The protein has a calculated MW of 40.9 kDa. The protein migrates as 55-66 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
• Proteinlength: Glu31-Arg369
• Endotoxin: Less than 0.1 EU per μg by the LAL method.
• Purity: >95% as determined by SDS-PAGE.
• Storage: Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
• Conjugation: Biotin
