Function
Binding to cells via a high affinity receptor, laminin is thought to mediate the attachment, migration and organization of cells into tissues during embryonic development by interacting with other extracellular matrix components. -
Sequence similarities
Contains 13 laminin EGF-like domains.
Contains 1 laminin IV type B domain.
Contains 1 laminin N-terminal domain. -
Domain
The alpha-helical domains I and II are thought to interact with other laminin chains to form a coiled coil structure.
Domains VI and IV are globular. -
Cellular localization
Secreted > extracellular space > extracellular matrix > basement membrane. Major component. - Information by UniProt

Western blot - Anti-Laminin beta 1 antibody [EPR3190(2)] (ab109293)All lanes : Anti-Laminin beta 1 antibody [EPR3190(2)] (ab109293) at 1/1000 dilution
Lane 1 : Wild-type HeLa cell lysate
Lane 2 : LAMB1 knockout HeLa cell lysate
Lysates/proteins at 20 µg per lane.
Performed under reducing conditions.
Predicted band size: 198 kDa
Observed band size: 200 kDa why is the actual band size different from the predicted?Lanes 1- 2: Merged signal (red and green). Green - ab109293 observed at 200 kDa. Red - Anti-alpha Tubulin antibody [DM1A] - Loading Control (ab7291) observed at 50 kDa.
ab109293 was shown to react with Laminin beta 1 in wild-type HeLa cells in western blot. Loss of signal was observed when knockout cell line ab265414 (knockout cell lysate ab257499) was used. Wild-type HeLa and LAMB1 knockout HeLa cell lysates were subjected to SDS-PAGE. Membrane was blocked for 1 hour at room temperature in 0.1% TBST with 3% non-fat dried milk. ab109293 and Anti-alpha Tubulin antibody [DM1A] - Loading Control (ab7291) overnight at 4°C at a 1 in 1000 dilution and a 1 in 20000 dilution respectively. 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 in 20000 dilution for 1 hour at room temperature before imaging.
