Immunofluorescent analysis of Cytokeratin Low Molecular Weight (green) showing staining in the cytoplasm of HepG2 cells. Formalin-fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 5-10 minutes and blocked with 3% BSA-PBS for 30 minutes at room temperature. Cells were probed with a Cytokeratin Low Molecular Weight monoclonal antibody (Product # MA5-13144) in 3% BSA-PBS at a dilution of 1:200 and incubated overnight at 4 °C in a humidified chamber. Cells were washed with PBST and incubated with a DyLight-conjugated secondary antibody in PBS at room temperature in the dark. F-actin (red) was stained with a flourescent red phalloidin and nuclei (blue) were stained with Hoechst or DAPI. Images were taken at a magnification of 60x.

MA5-13144 targets Cytokeratin Low Molecular Weight in WB, IF and IHC (P) applications and shows reactivity with Bovine, Chicken, Human, mouse, Non-human primate, Rabbit, and Rat samples. This antibody is not recommended for NIH-3T3 cells in immunofluorescent applications.
The MA5-13144 immunogen is human epidermal keratin.
Twenty human keratins are resolved with two-dimensional gel electrophoresis into acidic (pI <5.7) and basic (pI >6.0) subfamilies. The acidic keratins have molecular weights of 56.5, 55, 51, 50, 50', 48, 46, 45, and 40kDa. The basic keratins have molecular weights of 65-67, 64, 59, 58, 56 and 52kDa. Members of acidic and basic subfamilies are found together in pairs. The composition of keratin pairs varies with cell type, differentiation status and environment. Many studies have shown the usefulness of keratins as markers in cancer research and tumor diagnosis.
