Product Overview
Clone 21S05 is a rabbit monoclonal antibody that recognizes serine/arginine-rich splicing factor 3 (gene SRSF3) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF and flow cytometry. The predicted molecular weight is 19.3 kDa, and the supplier reports an observed band at about 19 kDa.
Serine/arginine-rich splicing factor 3 (SRSF3, also called SRp20) is one of the smallest SR proteins. It binds exonic motifs to promote inclusion of specific exons, can be recruited near m6A-modified sites through YTHDC1, and also acts as an adapter for nuclear export of mRNA.

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).
