Activity
Measured by its binding ability in a functional ELISA. Immobilized Human MICB at 2 μg/ml can bind Anti-MICA/B recombinant antibody (CSB-RA56059MA1HU). The EC50 is 1.087-1.369 ng/mL.
Description
MICB functions as a stress-induced ligand for the activating receptor NKG2D on natural killer cells and CD8+ T cells, making it a critical node in immune surveillance and tumor immunology. This mammalian-expressed protein spanning residues 23–309 captures the complete extracellular domain, ensuring native glycosylation and disulfide bond formation that preserve the conformational epitopes required for authentic receptor engagement. Functional ELISA validation demonstrates specific antibody binding with an EC50 of 1.087–1.369 ng/mL, confirming that the protein maintains its native structure and supports use in ligand-binding assays, therapeutic antibody epitope mapping, and competitive inhibition screens for NKG2D-targeting biologics. The combination of >95% purity and <1.0 EU/μg endotoxin meets the quality thresholds commonly required for surface plasmon resonance affinity characterization, bio-layer interferometry kinetic studies, and blocking antibody validation in immune checkpoint research.
