  • Immunofluorescence (IF) / fluorescent staining of mouse small intestine tissue using CoraLite® Plus 488-conjugated Cytokeratin 19 Polyc (CL488-10712)

    IF Staining of mouse small intestine using CL488-10712

    Adult mouse small intestine stained for Cytokeratin 19 (green, CL488-10712) and BMI1 (red, 10832-1-AP). BMI1 stains intestinal stem cells located at the base of the villi. As these stem cells differentiate into intestinal epithelial cells, they acquire Cytokeratin 19 expression. Cytokeratin 19 was conjugated to Coralite 488. Samples were fixed in 4% PFA, embedded in paraffin, and imaged on a confocal microscope. Image credit: @Immunofluorescence on Instagram.

  • Flow cytometry (FC) experiment of MCF-7 cells using CoraLite® Plus 488-conjugated Cytokeratin 19 Polyc (CL488-10712)

    FC experiment of MCF-7 using CL488-10712

    1X10^6 MCF-7 cells were intracellularly stained with 0.2 ug CoraLite® Plus 488 Anti-Human Cytokeratin 19 (CL488-10712) (red), or 0.2 ug Control Antibody. Cells were fixed with 4% PFA and permeabilized with Flow Cytometry Perm Buffer (PF00011-C).

Background Information

Keratins are a large family of proteins that form the intermediate filament cytoskeleton of epithelial cells. Keratin expression is highly regulated, tissue specific, and varies according to cell-state. Type I keratins consist of acidic, low molecular weight proteins with MW ranging from 40 kDa (KRT19) to 64 kDa (KRT9). Type 2 keratins consist of basic or neutral, high molecular weight proteins with MW from 52 kDa (KRT8) to 67 kDa (KRT18). Keratin 19 is a type I cytokeratin. It is a biochemical marker of skin stem cells in vivo and in vitro.
