Recombinant Human CD276 Protein, Fc-Avi-tagged, Biotinylated

• Cat.No.: CD276-1287H
• Product Overview: Biotinylated Human B7-H3, Fc Tag, Avi Tag is expressed from HEK293 cells. It contains AA Leu 29 - Pro 245 (Accession # Q5ZPR3-2). This protein carries a human IgG1 Fc tag at the C-terminus, followed by a Avi tag.

Specification

• Species: Human
• Source: HEK293
• Tag: Avi&Fc
• Protein Length: 29-245 a.a.
• Predicted N Terminal: Leu 29
• Form: Lyophilized from 0.22 um filtered solution in 49 mM Tris, 100 mM Glycine, 25 mM Arg, 150 mM NaCl, pH7.5, 10% trehalose.
• Molecular Mass: The protein has a calculated MW of 51.6 kDa. The protein migrates as 63-70 kDa under reducing condition (SDS-PAGE) due to glycosylation.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method.
• Purity: >90% as determined by SDS-PAGE.
• Characteristic: Biotinylation of this product is performed using Avitag technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin. The biotin to protein ratio is 0.5-1 as determined by the HABA assay.
• Stability: Samples are stable for up to twelve months from date of receipt at -70ºC.
• Storage: For long term storage, the product should be stored at lyophilized state at -20ºC or lower. Please avoid repeated freeze-thaw cycles. No activity loss is observed after storage at: 4-8ºC for 12 months in lyophilized state; -70ºC for 3 months under sterile conditions after reconstitution.
• 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℃ before opening to recover the entire contents.
