Recombinant Human B7-H3 Protein

SKU: orb2994418

Description

Recombinant Human B7 Homolog 3 is produced by our Mammalian expression system and the target gene encoding Leu29-Thr461 is expressed with a 6His tag at the C-terminus.

Key Properties

• Expression System: Human Cells
• Biological Origin: Human
• Biological Activity: ELISA: Immobilized Human B7-H3-His(Cat#orb2994418) at 2μg/ml (100 μl/well) can bind Anti-Human B7-H3 mAb(Cat#orb2993104 ). The ED50 of Anti-Human B7-H3 mAb(Cat#orb2993104) is 7.98 ng/ml. (Regularly tested). BLI: Loaded Anti-Human B7-H3 mAb-Fc(Cat#orb2993104) on Protein A Biosensor, can bind Human B7-H3-His(Cat#orb2994418) with an affinity constant of 0.7 nM as determined in BLI assay.

Storage & Handling

• Storage: Lyophilized protein should be stored at ≤ -20°C, stable for one year after receipt. Reconstituted protein solution can be stored at 2-8°C for 2-7 days. Aliquots of reconstituted samples are stable at ≤ -20°C for 3 months.
• Form/Appearance: Lyophilized
• Buffer/Preservatives: 0.2 μm filtered solution of PBS, pH 7.4.
• Reconstitution: Always centrifuge tubes before opening.Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100μg/ml. Dissolve the lyophilized protein in distilled water. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
• Expiration Date: 6 months from date of receipt.
