TMEM16A-HEK293 Recombinant Cell Line

Catalog #: 90230
Size: 2 vials
Species: Human
Genbank #: NM_018043

Calcium-activated chloride channels (CaCCs) are major regulators in numerous physiological processes including sensory transduction, epithelial secrection, cardiac and neutonal excitation, and smooth muscle contraction.

TMEM16A (ANO1), a member of a family of putative plasma membrane proteins, is identified as a CaCC that is activated by intracellular Ca2+ and Ca2+-mobilizing stimuli. It has eight putative transmembrane segments without domains evidently involved in calcium regulation. The relative permeability of TMEM16A to monovalent anions is NO3- > I- > Br- > Cl- > F-.

Stable, recombinant HEK293 cell line expressing human TMEM16A (transmembrane protein 16A, also called anoctamin 1, calcium-activated chloride channel (ANO1), accession number NM_018043).
TMEM16A, transmembrane protein 16A, anoctamin 1, calcium-activated chloride channel, ANO1
Supplied As:
Each vial contains ~1 X 106 cells in 1 ml of 10% DMSO.
Biological Activity:
N-terminal FLAG tagged human TMEM16A channel has been stably expressed in HEK293 cell line and its expression was confirmed by Western blotting. The CaCC activity of TMEM16A was characterized by an assay based on halide-sensitive yellow fluorescent protein (YFP) mutant whose fluorescence is quenched by increasing halide concentration. When TMEM16A-expressed HEK293 cells were stimulated with ionomycin to raise the intracellular level of Ca2+, TMEM16A produced I influx in HEK293 that triggered the rapid decrease of fluorescence of transfected YFP mutant. The ionomycin-induced I influx through TMEM16A was blocked by niflumic acid, a CaCC channel blocker.

Mycoplasma Testing:
The cell line has been screened using the PCR-based VenorGeM Mycoplasma Detection kit (Sigma Aldrich) to confirm the absence of Mycoplasma species.
Growth Media:

Thaw Medium 1 (BPS Cat. #60187): MEM medium (Hyclone #SH30024.01) supplemented with 10% FBS (Invitrogen #26140-079), 1% non-essential amino acids (Hyclone #SH30238.01), 1 mM Na pyruvate (Hyclone #SH30239.01), 1% Penicillin/Streptomycin (Hyclone SV30010.01)

Growth Medium 1B (BPS Cat. #79531): Thaw Medium 1 (BPS Cat. #60187) plus 400 μg/ml of Geneticin (invitrogen #11811031) to ensure the recombinant expression is maintained.
