Anti - NaPi-4, NT, aa71-86 (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.

Peptide is 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. Control peptide, because of its low MW (<3kD), is not suitable for Western. It should be used for ELISA or antibody blocking (use 5-10 ug per 1 ul of antiserum or 1 ug of aff pure IgG) to confirm antibody specificity
