      The Life Science industry has been in the grips of a reproducibility crisis for a number of years. Abcam is leading the way in addressing the problem with our range of recombinant monoclonal antibodies and knockout edited cell lines for gold-standard validation.

      One factor contributing to the crisis is the use of antibodies that are not suitable. This can lead to misleading results and the use of incorrect data informing project assumptions and direction. To help address this challenge, we have introduced an application and species grid on our primary antibody datasheets to make it easy to simplify identification of the right antibody for your needs.

      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. One possible explanation is that Salmonella typhi has been shown to use CFTR to enter intestinal epithelial cells and that delta F508 heterozygote and homozygote mice showed 86% and 100% reductions in S. typhi intestinal submucosal uptake.

    靶标

    • 功能

      Involved in the transport of chloride ions. May regulate bicarbonate secretion and salvage in epithelial cells by regulating the SLC4A7 transporter.
    • 组织特异性

      Found on the surface of the epithelial cells that line the lungs and other organs.
    • 疾病相关

      Defects in CFTR are the cause of cystic fibrosis (CF) [MIM:219700]; also known as mucoviscidosis. CF is the most common genetic disease in the Caucasian population, with a prevalence of about 1 in 2'000 live births. Inheritance is autosomal recessive. CF is a common generalized disorder of exocrine gland function which impairs clearance of secretions in a variety of organs. It is characterized by the triad of chronic bronchopulmonary disease (with recurrent respiratory infections), pancreatic insufficiency (which leads to malabsorption and growth retardation) and elevated sweat electrolytes.
      Defects in CFTR are the cause of congenital bilateral absence of the vas deferens (CBAVD) [MIM:277180]. CBAVD is an important cause of sterility in men and could represent an incomplete form of cystic fibrosis, as the majority of men suffering from cystic fibrosis lack the vas deferens.
    • 序列相似性

      Belongs to the ABC transporter superfamily. ABCC family. CFTR transporter (TC 3.A.1.202) subfamily.
      Contains 2 ABC transmembrane type-1 domains.
      Contains 2 ABC transporter domains.
    • 结构域

      The PDZ-binding motif mediates interactions with GOPC and with the SLC4A7, SLC9A3R1/EBP50 complex.
    • 翻译后修饰

      Phosphorylated; activates the channel. It is not clear whether PKC phosphorylation itself activates the channel or permits activation by phosphorylation at PKA sites.
      Ubiquitinated, leading to its degradation in the lysosome. Deubiquitination by USP10 in early endosomes, enhances its endocytic recycling.

    Asked on Jul 10 2006

    Answer

    I'm very sorry to hear one of your customers is experiencing problems with ab2916, indeed CFTR is known to be present in sperm and should be detectable with ab2916. I think the problem comes from the fixation which is damaging the epitopes. I would recommend to fix the cells in methanol for 5 minutes at -20C. I enclose below the protocol used by Walker et al (Walker J et al. Production and characterisation of monoclonal and polyclonal antibodies to different regions of the cystic fibrosis transmembrane conductance regulator (CFTR): detection of immunologically related proteins. J Cell Sci 108 (Pt 6):2433-44 (1995)): Wash cells 3x PBS, then fixe and permeabilize by incubation in methanol at -20°C for 5 min. Incubate coverslips in PBS/0.2% BSA for 5 min followed by a PBS wash and incubation with primary antibody in PBS/0.2% BSA for 1 h at room temperature. After washing in PBS/0.2 % BSA to remove excess primary antibody, incubate cells in secondary antibody. Please let me know if the customer still has problems with this protocol and I can offer you a replacement vial or credit note,

    Question

    DESCRIPTION OF THE PROBLEM I have just tried ab2916 on sheep kidney proteins and got a large number of non-specific bands and no band at the expected 170kDa for CFTR. In your product sheet, Western Blotting was not mentioned, but I noticed that ab2784 is quite the same antibody, and the antigen peptide used to create it is the same as that of ab2916. However, in the ab2784 product sheet, Western Blotting was mentioned. Are there any differences between these two antibodies in terms of whether it would work for immunohistochemistry and/or Western Blotting ?

    Asked on Jun 23 2005

    Answer

    Thank you for contacting us for some advice on ab2916 and ab2784. You are correct, both antibodies were made using the same immunizing peptide, however they are raised in different species and more importantly we do not know if they recognise the same epitope within aa103-117, so a different epitope could explain the difference. We have not tested ab2916 in WB and from your feedback it does appear that it does not work in that application, would you please consider leaving a review on this antibody so we can add this information for future users? We reward reviews (negative and positive) with 100 Abcam points which can be used for a number of gifts. I hope the above information will help you, please do not hesitate to contact me again if you require further assistance,

    Question

    can you please tell me if the peptide used to make this antibody was made from the intracellular or extracellular portion of the protein?

    Asked on Jun 20 2005

    Answer

    Both ab2916 and ab2784 are made from the same synthetic peptide corresponding to amino acid residues 103-117. Ab2784 corresponds to amino acid residues 103-117 found in the first extracellular loop of human and rabbit CFTR. So, it appears that ab2916 was made from the extracellular portion. I hope this information helps; if you have any additional questions, please contact us again.

    Asked on Apr 15 2005

    Answer

    I'm sorry to hear you are experiencing problems with ab2916. This antibody has not been tested for western blotting, it is therefore difficult to find out what the problem might be. A litterature search about CFTR enabled me to find that the lysis buffer used to extract the protein from K562 cells is the following NP40 based buffer: 50 mM HEPES, 250 mM NaCl, 1 mM EDTA, 1% NP-40, 1 mM PMSF, and 1 mM DTT. This information was from the reference "CFTR in K562 human leukemic cells. Assef YA, Damiano AE, Zotta E, Ibarra C, Kotsias BA. Am J Physiol Cell Physiol. 2003 Aug;285(2):C480-8." The article continues: "Nuclei and unbroken cells were removed with centrifugation (6,000 g for 15 min at 4°C). Total protein in each sample was quantified using the bicinchoninic acid assay (BCA Protein, Pierce Chemical). For Western blot studies, 100 ug of total proteins from K562 cells and 50 ug of total proteins from T84 cells were dissolved in loading buffer (4% sodium dodecil sulfate, 0.125 M Tris-HCl, pH 6.8, 0.2 M dithiothreitol, 0.02% bromophenol blue, and 20% glycerol). The preparation was heated to 90°C for 2 min, resolved on 7.5% polyacrylamide gel, and electrotransferred onto nitrocellulose membranes(Hybond ECL, Amersham Pharmacia Biotech, UK)." I would recommend trying a range of dilutions (e.g. 1/100-1/1000) and incubating the antibody overnight at 4C. I hope the above information will help you, please let me know if you require further assistance,
