Anti - NaPi-4 (Npt2a)

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 opossum Napi-4/Npt2a. This sequence is not conserved in mouse, rat, human and other species Npt2a. No significant sequence homology is observed with other Pi-transporters (Type-I, III, or IV) transporters. Antibody crossreactivity in various species is not established.
