Product Overview
This rabbit polyclonal antibody targets MHC class I polypeptide-related sequence A (gene MICA) in human samples and is validated for Western blot. The predicted molecular weight is 42.9 kDa, and the supplier reports an observed band at about 45 kDa.
MICA is a stress-induced, MHC class I-like membrane protein that does not present antigen. Infection, DNA damage and transformation increase its surface expression, where it binds the activating receptor NKG2D on natural killer cells, γδ T cells and CD8+ T cells, so it is widely studied in tumor immune surveillance and innate immunity.

Validated Applications
| Western blot | 0.1–0.5 µg/mL (Human) |
|---|
Samples with a confirmed band (WB): human Raji cells, human SGC-7901 cells, human SW620 cells, huamn Jurkat cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Immunogen
Synthetic peptide from the C-terminal region of human MICA.
Reactivity Notes
The supplier lists reactivity with human. UniProt places MHC class I polypeptide-related sequence A in the cell membrane and cytoplasm. Tissue expression noted by UniProt (human): Widely expressed with the exception of the central nervous system where it is absent. The samples tested by the supplier (listed above) are a practical starting point for positive controls.

Customization & Add-ons: Can’t find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
