Tested Applications

• Positive WB detected in: Y79 cells, mouse lung tissue
• Positive IP detected in: Y79 cells
• Positive IHC detected in: human gliomas tissue; Note: suggested antigen retrieval with TE buffer pH 9.0; (*) Alternatively, antigen retrieval may be performed with citrate buffer pH 6.0

Recommended dilution

• Western Blot (WB): WB : 1:200-1:1000
• Immunoprecipitation (IP): IP : 0.5-4.0 ug for 1.0-3.0 mg of total protein lysate
• Immunohistochemistry (IHC): IHC : 1:50-1:500

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

Background Information

CD133, also known as PROM1 (prominin-1) or AC133, belongs to the prominin family. CD133 is a transmembrane glycoprotein with an NH2-terminal extracellular domain, five transmembrane loops and a cytoplasmic tail. The expression of CD133 has been reported in hematopoietic stem cells, endothelial progenitor cells, neuronal and glial stem cells, suggesting the potential role of CD133 as a cell surface marker of adult stem cells. CD133 has also been reported as a marker of cancer stem cells in various human tumors. This antibody recognizes transcript variant 1,2,4,7 (UNIPROT has updated the info of isoforms)of CD133.
