Our Abpromise guarantee covers the use of ab77801 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
IP Use at an assay dependent dilution. Precipitates PAGE bands of 66, 76, 120, 135 and 200kDa (reduced) or 66, 110, 125, 130 and 190kDa (non-reduced) from surface-biotinylated SCC9 cells.
IHC-Fr Use at an assay dependent dilution.
Flow Cyt Use 1µg for 106 cells.
Inhibition Assay Use at an assay dependent dilution. Inhibits SCC9 cell adhesion to human and EHS laminin and laminin GD-2 peptide, but not to type IV collagen or fibronectin. Does not inhibit SKOV-3 cell adhesion to laminin, fibronectin or type IV collagen.
  • Application notesIs unsuitable for IHC-P.
  • Target

    • FunctionIntegrin alpha-6/beta-4 is a receptor for laminin. It plays a critical structural role in the hemidesmosome of epithelial cells.
    • Tissue specificityIntegrin alpha-6/beta-4 is predominantly expressed by epithelia. Isoform beta-4D is also expressed in colon and placenta. Isoform beta-4E is also expressed in epidermis, lung, duodenum, heart, spleen and stomach.
    • Involvement in diseaseDefects in ITGB4 are a cause of epidermolysis bullosa letalis with pyloric atresia (EB-PA) [MIM:226730]; also known as junctional epidermolysis bullosa with pyloric atresia (PA-JEB) or aplasia cutis congenita with gastrointestinal atresia. EB-PA is an autosomal recessive, frequently lethal, epidermolysis bullosa with variable involvement of skin, nails, mucosa, and with variable effects on the digestive system. It is characterized by mucocutaneous fragility, aplasia cutis congenita, and gastrointestinal atresia, which most commonly affects the pylorus. Pyloric atresia is a primary manifestation rather than a scarring process secondary to epidermolysis bullosa.
      Defects in ITGB4 are a cause of generalized atrophic benign epidermolysis bullosa (GABEB) [MIM:226650]. GABEB is a non-lethal, adult form of junctional epidermolysis bullosa characterized by life-long blistering of the skin, associated with hair and tooth abnormalities.
    • Sequence similaritiesBelongs to the integrin beta chain family.
      Contains 1 Calx-beta domain.
      Contains 4 fibronectin type-III domains.
      Contains 1 PSI domain.
      Contains 1 VWFA domain.
    • DomainThe fibronectin type-III-like domains bind BPAG1 and plectin and probably also recruit BP230.

    Anti-Integrin beta 4 antibody [ASC-8] images

    • Overlay histogram showing A431 cells stained with ab77801 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab77801, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed.
