  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.

  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).

Tested Applications

• Positive IF detected in: mouse small intestine tissue, HeLa cells, HepG2 cells
• Positive FC (Intra) detected in: MCF-7 cells

Recommended dilution

• Immunofluorescence (IF): IF : 1:10-1:100
• Flow Cytometry (FC) (INTRA): FC (INTRA) : 0.20 ug per 10^6 cells in a 100 µl suspension

It is recommended that this reagent should be titrated in each testing system to obtain optimal results.

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.
