Description Clone REA909 recognizes the human CD338 antigen, a multi-pass membrane protein which is also known as ATP-binding cassette sub-family G member 2 (ABCG2) or breast cancer resistance protein (BCRP). CD338 is a member of the ATP-binding cassette (ABC) transporter superfamily and known to contribute to multidrug resistance in cancer chemotherapy. It is highly expressed on primitive stem cells as identified by the side-population phenotype, which is characterized by the efflux of chemicals, including the fluorescent dye Hoechst 33342 and Rhodamine 123. Among ABC transporters that are known to cause multidrug resistance, CD338 is particularly interesting for its potential role in protecting cancer stem cells and its complex oligomeric structure. | Additional information: Clone REA909 displays negligible binding to Fc receptors.
About ABCG2 and FITC
ABCG2 The membrane-associated protein encoded by this gene is included in the superfamily of ATP-binding cassette (ABC) transporters. ABC proteins transport various molecules across extra- and intra-cellular membranes. ABC genes are divided into seven distinct subfamilies (ABC1, MDR/TAP, MRP, ALD, OABP, GCN20, White). This protein is a member of the White subfamily. Alternatively referred to as a breast cancer resistance protein, this protein functions as a xenobiotic transporter which may play a major role in multi-drug resistance. It likely serves as a cellular defense mechanism in response to mitoxantrone and anthracycline exposure. Significant expression of this protein has been observed in the placenta, which may suggest a potential role for this molecule in placenta tissue. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Apr 2012]
FITC Fluorescein isothiocyanate (FITC) has an excitation peak at 495 nm and an emission peak at 519 nm. The name FITC is a misnomer in that the isothiocyanate is a reactive form of this dye. Once FITC is conjugated to an antibody, it is simply Fluorescein conjugated. FITC is one of the most widely used dyes for fluorescent applications, therefore most instruments come standard with a 488 nm laser and FITC filter set up. FITC is commonly conjugated to secondary antibodies and used in applications such as flow cytometry, immunocytochemistry, and immunohistochemistry. FITC is relatively dim, sensitive to photobleaching and it is susceptible to changes is pH. There are better performing alternatives to FITC, like Vio®Bright 515, Alexa Fluor™ 488, iFluor® 488, CF®488A and DY-488. FITC is a long-time generic dye with no sole manufacturer or trademark.
