Nucleoprotein Interactor-1, hSRP-1 (NPI-1)

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.

Specific for the NPI-1 (nucleoprotein interactor-1, karyopherin alpha 1, hSRP1) protein. On Western blots, it identifies a band at ~60kD. Reactivity has been confirmed with human HeLa and MDBK cell lysates.
