CD133 Antibody (MA5-18323) in WB
Western Blot was performed using Anti-CD133 Monoclonal Antibody (5E3) (Product # MA5-18323) and a 133 kDa band corresponding to Prominin-1 was observed across cell lines tested except HeLa and SK-O-V3 which are reported to be low or negative for CD133 expression. Membrane enriched extracts (30 µg lysate) of NTERA-2 cl.D1 (Lane 1), Caco-2 (Lane 2), HT-29 (Lane 3), HeLa (Lane 4) and SK-O-V3 (Lane 5) were electrophoresed using NuPAGE™ 4-12% Bis-Tris Protein Gel (Product # NP0322BOX). Resolved proteins were then transferred onto a Nitrocellulo... View More

Target Information
The CD133 (AC133) antigen is a 97 kDa glycoprotein, with 5 transmembrane domains, that shows up as a 120 kDa band on protein gels due to glycosylation. CD133 is a cell surface marker expressed by immature hematopoietic stem cells but not mature blood cells. In addition to hematopoietic stem and progenitor cells, CD133 has been found to be a marker for other stem and progenitor cells including neural and embryonic stem cells. CD133 has been shown to be expressed in cancers, including some leukemias and brain tumors, that may be derived from stem cells. Low level expression could also be detected in the kidney, pancreas, placenta, and fetal liver. Mutations in this gene have been shown to result in retinitis pigmentosa and Stargardt disease. Expression of the CD133 gene is also associated with several types of cancer. CD133 is expressed from at least five alternative promoters that are expressed in a tissue-dependent manner, and multiple transcript variants encoding different isoforms have been found.
