    • 機能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.
    • 配列類似性Belongs to the integrin alpha chain family.
      Contains 7 FG-GAP repeats.
    • ドメインThe SG1 motif is involved in binding to chondroitin sulfate glycosaminoglycan and cell adhesion.
    • 翻訳後修飾Phosphorylation on Ser-1027 inhibits PXN binding.
    • 細胞内局在Membrane.

    Anti-Integrin alpha 4 antibody [44H6] 画像

    • ab220 staining Integrin alpha 4 in wild-type HAP1 cells (top panel) and Integrin alpha 4 knockout HAP1 cells (bottom panel). 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.

    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.

    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,

    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 ...

    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...
