SLC4A4 takes part in the regulation of bicarbonate secretion and absorption and intracellular pH. Mutations in SLC4A4 gene are associated with proximal renal tubular acidosis. SLC4A4 is involved in the regulation of intracellular pH in several cell types. SLC4A4 Isoform 2 is particularly expressed in kidney at the level of proximal tubules.
Amino acid subsitution in SLC4A4 results in an increase of chloride transport.
NBC1 takes part in proximal renal tubular acidosis and ocular abnormalities.
Store at 4℃ if entire vial will be used within 2-4 weeks.
Store， frozen at -20℃ for longer periods of time.
For long term storage it is recommended to add a carrier protein （0.1% HSA or BSA）.
Avoid multiple freeze-thaw cycles.
