    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.

    • Function

      Integrins alpha-4/beta-1 (VLA-4) and alpha-4/beta-7 are receptors for fibronectin. They recognize one or more domains within the alternatively spliced CS-1 and CS-5 regions of fibronectin. They are also receptors for VCAM1. Integrin alpha-4/beta-1 recognizes the sequence Q-I-D-S in VCAM1. Integrin alpha-4/beta-7 is also a receptor for MADCAM1. It recognizes the sequence L-D-T in MADCAM1. On activated endothelial cells integrin VLA-4 triggers homotypic aggregation for most VLA-4-positive leukocyte cell lines. It may also participate in cytolytic T-cell interactions with target cells.
    • Sequence similarities

      Belongs to the integrin alpha chain family.
      Contains 7 FG-GAP repeats.
    • Domain

      The SG1 motif is involved in binding to chondroitin sulfate glycosaminoglycan and cell adhesion.
    • Post-translational
      modifications

      Phosphorylation on Ser-1027 inhibits PXN binding.
    • Cellular localization

The cells were fixed with 4% formaldehyde (10min), permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated with ab220 at 5μg/ml concentration and ab220272 at 1/250 dilution (shown in pseudo colour red) overnight at +4°C, followed by a further incubation at room temperature for 1h with a goat secondary antibody to Mouse IgG (Alexa Fluor® 488) (ab150117) at 2 μg/ml (shown in green). Nuclear DNA was labelled in blue with DAPI.

      Question

      Which portion of the integrin alpha4 that the antibody will detect? Is it the extracellular domain, or cytplasmic domain?

      Asked on Dec 12 2008

      Answer

      Thank you for your enquiry. This product recognises the extracellular portion of integrin alpha 4. However, since epitope mapping was never done, there is no information on the exact epitope sequence.

      Answer

      Thank you for your enquiry regarding ab220. We have not mapped the epitope region recognized by this antibody therefore we do not know which region is recognized by the antibody. Sorry I couldn't help you more on this occasion,

      Question

      follow up to previous enquiry: The two different positive controls were histag versions of human integrin alpha 4, both were loaded at approximately 50ng. It is possible there isn't enough protein in my samples but that doesn't explain why I'm not detecting my positive controls. Can you suggest a good starting dilution for this antibody also?

      Answer

      Thank you for your email. We have had feedback from a customer who used this antibody at a 1:200 dilution for Western blotting. I'm really not sure why this antibody is not working for you, and can offer (if you have purchased the antibody in the past 90 days) a replacement vial to try or a refund or credit note. Please let me know how you would like to proceed.

      follow up to previous enquiry: To answer your questions reqarding inquirey 735273 1. My transfer was good because my molecular weight markers transfer fine and I ran a number of gels at the same time and they all worked fine (different antibodys) 2. I found the lot number and it is 146463 3. I don't know the amount if any protein was loaded, I am determing mammalian cell transfection of the recombinant integrin alpha 4 from cell culture supernatant and am trying to verify expression.

      Answer

      Thank you for your email. I noticed in your previous email that you mentioned for a positive control, "tried 2 different previously verified positive controls." Can you please elaborate on that? For your other samples, the soluble integrin alpha 4 secreted into cell supernatant, I wonder if there's enough present there to be detected by this antibody. Thanks again, and I look forward to hearing from you.

      Answer

      Thank you for your enquiry and I'm sorry to hear that you are experiencing difficulty with this antibody. Did you determine how much protein was loaded onto the gel? Also, do you know if the protein transferred properly to the membrane? What was the batch number (located on the vial) or the Abcam order number or purchase order number that was used when you purchased ab220? Thank you, and I look forward to hearing from you.
