Gene Information

human ... CFTR(1080)

General description

CFTR (Cystic Fibrosis Transmembrane Regulator) is an integral membrane protein shown to be involved in the transport of chloride ions. It is found on the surface of the epithelial cells lining the lungs and other organs. CFTR defects are the cause of cystic fibrosis. Cystic Fibrosis (CF) is a common lethal genetic disease caused by mutations of the gene coding for the cystic fibrosis transmembrane conductance factor, a cAMP regulated chloride channel. Approximately 70% of all CF cases share the deletion of a phenylalanine at position 508 (delta F508), which results in abnormal chloride transport. Since the CF mutation is lethal, most often by lung and liver disease, it raises the question of why this genetic disease remains as common as it is.

Specificity

Quality

Routinely evaluated by western blot on human T84 colon carcinoma epithelial RIPA cell lysates or from CFTR-transfected BHK2.

Western Blot Analysis:
0.5-2 µg/mL of this lot detected CFTR from 20-50 µg of human T84 colon carcinoma epithelial RIPA cell lysates. 0.5-2 µg/mL of a previous lot detected CFTR from CFTR-transfected BHK (Haardt, M., 1999).
Note: Do not boil the lysate. Instead incubate at 37°C for 30 minutes. CFTR can run as a diffuse protein on SDS-PAGE.

Target description

170 kDa

Physical form

Format: Purified
Protein G Purified
Purified mouse monoclonal IgG1 in buffer containing 0.1 M Tris-glycine, pH 7.4, 0.15 M NaCl, 0.05% sodium azide and 30% glycerol.

Storage and Stability

Stable for 1 year at -20°C from date of receipt.

Handling Recommendations:
Upon receipt, and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance. Note: Variability in freezer temperatures below -20°C may cause glycerol-containing solutions to become frozen during storage.

Analysis Note

Control
T84 cell lysate.

Other Notes

Concentration: Please refer to the Certificate of Analysis for the lot-specific concentration.

We evaluated whether small molecule correctors could rescue four nucleotide-binding domain 1 (NBD1) mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene (A455E, S492F, ΔI507, and R560T). We first transfected Cos-7 cells (green monkey kidney cells) with A455E, S492F, ΔI507
