Product Overview
This rabbit polyclonal antibody targets FACT complex subunit SSRP1 in human, monkey, mouse and rat samples and is validated for Western blot, IHC, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 81.1 kDa, and the supplier reports an observed band at about 92 kDa.
FACT complex subunit SSRP1 pairs with SUPT16H to form FACT, a histone chaperone that reorganizes nucleosomes. FACT temporarily removes and restores histone H2A-H2B dimers so that RNA polymerase II and replication and repair machinery can pass through chromatin, making it important for transcription elongation and DNA replication.

Samples with a confirmed signal (flow cytometry): U251 cells.
Immunogen
Recombinant human SSRP1 fragment (Ala2–Arg381), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, monkey, mouse and rat. UniProt places FACT complex subunit SSRP1 in the nucleus and chromosome. 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).
