Anti - NaPi-1 (Npt1)

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.

The NPT11-P peptide is 93% conserved in 86% conserved in rat, 78% in human NPT1/Napi-4/NPT4 and 78% in rabbit Napi-1/NPT1. No significant sequence homology of NPT11-P is observed with other Pi-transporters (Type-II-IV) transporters. Antibody crossreactivity in various species is not established.
