Product Overview
This rabbit polyclonal antibody detects nuclear mitotic apparatus protein 1 (gene NUMA1) in human, mouse, rat and monkey samples and is validated for Western blot, IHC, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 238.3 kDa, and the supplier reports an observed band at about 270 kDa.
NuMA (NUMA1) is a large microtubule-binding protein that is nuclear in interphase and moves to the spindle poles in mitosis. It tethers microtubule minus ends at the poles and works with dynein and LGN to orient the spindle, so it is studied in cell division, asymmetric division and nuclear organization.

Samples with a confirmed signal (flow cytometry): RT4 cells.
Immunogen
Recombinant human NUMA/NUMA1 fragment (Met1–Glu1954), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse, rat and monkey. UniProt places nuclear mitotic apparatus protein 1 in the nucleus, nucleus matrix, chromosome and cytoplasm. 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).
