  • RelevanceLAPTM4B belongs to the LAPTM4/LAPTM5 transporter family. It has an active role in disease progression of malignant cells and is involved in cell proliferation and multidrug resistance. The genetic polymorphism of LAPTM4B is a potential risk factor for the development of colon cancer and gastric cancer. The research results also indicated that LAPTM4B may be a clinically useful prognostic indicator for ovarian carcinoma and may play a role in human hepatocellular carcinoma.

  • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human pineal tissue labelling LAPTM4B with ab82810 at 1/100. A Cy3-conjugated donkey anti-rabbit IgG (1/200) was used as the secondary antibody. Positive staining shown in the membrane and cytoplasm of processes of pinealocytes and intersticial cells. Magnification: 20X. Exposure time: 0.5 - 2.0 seconds. Left - DAPI. Middle - LAPTM4B. Right - Merge.

    Predicted band size : 35 kDa
    Observed band size : 33 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 28 kDa. We are unsure as to the identity of these extra bands.
    Gel concentration: 12%
  • ICC/IF image of ab82810 stained Hek293 cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab82810, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899, DyLight® 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
