Anti-CFTR Antibody, clone MM13-4

170 kDa

CFTR (Cystic Fibrosis Transmembrane conductance Regulator) is a 170 kDa chloride (Cl-) channel that regulates salt and water transport across epithelial tissues, where it modulates production of mucus, sweat, saliva, tears, and digestive enzymes. Cystic fibrosis patients have mutations in this protein, resulting in defective in ion transport. Symptoms include reduced transport of sodium chloride (saltier sweat) and digestive and respiratory disorders caused by thicker mucus. CFTR mutations are also associated with congenital bilateral absence of the vas deferens in males.

Synthetic peptide (RKGYRQRLELSD) corresponding to residues 25-36 of human cystic fibrosis transmembrane conductance regulator (CFTR). The immunizing sequence is identical in monkey and rabbit, has 11/12 identical amino acids in sheep, cow and frog, 10/12 identity in mouse and 9/12 identity in rat. Clone MM13-4.

Anti-CFTR Antibody, clone MM13-4 detects level of CFTR & has been published & validated for use in IC, IP & WB.

Immunoprecipitation:

This antibody recognizes CFTR, Mr 170kDa. Two additional proteins were detected, Mr 52 and 38 kDa, in CFTR-transfected BHK cell lysates.

Format: Purified

Protein A purified

Purified mouse monoclonal IgG1k in buffer containing 0.02M phosphate buffer, pH 7.6, 0.25M NaCl, and 0.1% sodium azide.

Stable for 1 year at 2-8°C from date of receipt.

Control
Pancreas. RIPA cell lysates

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

Western Blot Analysis:
0.5-2 μg/mL of this lot detected CFTR in human T84 colon carcinoma epithelial RIPA cell lysates. A previous lot detected CFTR in CFTR-transfected BHK.

Note: CFTR can run as a diffuse protein on SDS-PAGE.

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