NKCC1 (N-16): sc-21545
BACKGROUND
Na-K-Cl cotransporters (NKCC) are channel proteins that aid in Store at 4° C, do not freeze; stable for one year from the date of the transcellular movement of chloride across both secretory and absorptive epithelia (1,2). The 170 kDa NKCC1 is expressed inmuscle cells, neurons, and red blood cells (1-3). In the basolateral RESEARCH USE
membrane of secretory epithelia, NKCC1 mediates active chloride For research use only, not for use in diagnostic procedures.
