Recombinant Human CD276 protein, Fc-tagged

• Cat.No.: CD276-303H
• Product Overview: Recombinant Human CD276 (Gly27-Thr461) protein was fused to human IgG1 Fc tag at C-terminus and expressed in human 293 cells (HEK293).

Specification

• Description: Human B7 homolog 3 (B7-H3) is a member of the B7 family of immune proteins that provide signals for the regulation of immune responses. Other family members include B7-1, B7-2, B7-H1/PD-L1, B7-H2, and PD-L2. B7 family proteins are type I transmembrane immunoglobulin (Ig) superfamily members that contain extracellular Ig V‑like and Ig C‑like domains with a short cytoplasmic tail. Termed 4IgB7-H3 or B7-H3b, this molecule has two additional Ig-like domains (one V‑type and one C‑type) and shows a ubiquituous expression pattern.
• Source: HEK293
• Species: Human
• Tag: human IgG1 Fc
• Predicted N Terminal: Gly27
• Form: Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5, 10% trehalose.
• Molecular Mass: The protein has a calculated MW of 73.1 kDa. The protein migrates as 100-110 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
• Protein length: Gly27-Thr461
• Endotoxin: Less than 1.0 EU per μg by the LAL method.
• Purity: >95% as determined by reduced SDS-PAGE.
• Storage: For long term storage, the product should be stored at lyophilized state at -20 centigrade or lower.
  Please avoid repeated freeze-thaw cycles.
  This product is stable after storage at:
  -20 to -70 centigrade for 12 months in lyophilized state;
  -70 centigrade 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.
