SR, p20 (Non-snRNP Splicing Factor)

May be stored at 4 °C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and add glycerol (40-50%). Freeze at -20 °C. Aliquots are stable for at least 12 months at -20 °C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.

Speci c for the non-snRNP splicing factor SRp20 and does not crossreact with other SR protein family members. Reactivity is not dependent upon phosphorylation of the SRp20 protein. Species Crossreactivity: human.
