Anti-SNRPA Antibody

SNRPA (Small Nuclear Ribonucleoprotein Polypeptide A) forms the protein core of the U1 small nuclear ribonucleoprotein complex, an essential assembly of the spliceosome that recognizes the 5' splice site during pre-mRNA processing. This unconjugated rabbit polyclonal reagent from Antibodies.com is raised against SNRPA and validated for Western blot and immunohistochemistry workflows across human, mouse, and rat samples. The antibody is supplied as a 100 µl liquid aliquot at 1 mg/ml in PBS with 0.1% sodium azide and 50% glycerol as a cryoprotective additive; the high glycerol content keeps the preparation liquid at standard freezer temperatures, and sodium azide protects against microbial contamination during storage. As a primary antibody, it is intended for research use to investigate U1 snRNP biogenesis, spliceosome assembly, and RNA processing mechanisms in cell and tissue models.
