General notes
ab239898 is the carrier-free version of ab81280.
Our carrier-free antibodies are typically supplied in a PBS-only formulation, purified and free of BSA, sodium azide and glycerol. The carrier-free buffer and high concentration allow for increased conjugation efficiency.
This conjugation-ready format is designed for use with fluorochromes, metal isotopes, oligonucleotides, and enzymes, which makes them ideal for antibody labelling, functional and cell-based assays, flow-based assays (e.g. mass cytometry) and Multiplex Imaging applications.
Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with <1 minute hands-on-time and 100% antibody recovery: available for fluorescent dyes, HRP, biotin and gold.
This product is compatible with the Maxpar® Antibody Labeling Kit from Fluidigm, without the need for antibody preparation. Maxpar® is a trademark of Fluidigm Canada Inc.
This product is a recombinant monoclonal antibody, which offers several advantages including:
- - High batch-to-batch consistency and reproducibility
- - Improved sensitivity and specificity
- - Long-term security of supply
- - Animal-free production
Our RabMAb® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMAb® patents.

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
modificationsPhosphorylation on Ser-1027 inhibits PXN binding. -

This data was developed using ab81280, the same antibody clone in a different buffer formulation.
Lane 1: Integrin alpha 4 knockout HAP1 cell lysate (20 µg)
Lane 2: Wild-type HAP1 cell lysate (20 µg)
Lanes 1 and 2: Merged signal (red and green). Green - ab81280 observed at 150 kDa. Red - loading control, ab8226, observed at 42 kDa.
ab81280 was shown to recognize Integrin alpha 4 in wild-type HAP1 cells along with additional cross-reactive bands. No bands were observed when Integrin alpha 4 knockout samples were used. Wild-type and Integrin alpha 4 knockout samples were subjected to SDS-PAGE. ab81280 and ab8226 (loading control to beta actin) were diluted 1/2000 and 1/1000 respectively and incubated overnight at 4°C. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1/10,000 dilution for 1hr at room temperature before imaging.

Predicted band size: 150 kDa
Observed band size: 150 kDaThis data was developed using ab81280, the same antibody clone in a different buffer formulation.
Lanes 1 - 2: Merged signal (red and green). Green - ab81280 observed at 150 kDa. Red - loading control, ab8245, observed at 37 kDa.
This blot was produced using a 4-12% Bis-tris gel under the MOPS buffer system. The gel was run at 200V for 50 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using Licor blocking buffer before being incubated with ab81280 and ab8245 (loading control) overnight at 4°C. Antibody binding was detected using Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed (ab216776) at a 1:10000 dilution for 1hr at room temperature and then imaged.
