About ABCA7
The protein encoded by this gene is a member of 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 ABC1 subfamily. Members of the ABC1 subfamily comprise the only major ABC subfamily found exclusively in multicellular eukaryotes. This full transporter has been detected predominantly in myelo-lymphatic tissues with the highest expression in peripheral leukocytes, thymus, spleen, and bone marrow. The function of this protein is not yet known; however, the expression pattern suggests a role in lipid homeostasis in cells of the immune system. [provided by RefSeq, Jul 2008]

About Alexa Fluor 532
Alexa Fluor™ 532 (AF532, Alexa 532) has an excitation peak at 532 nm and an emission peak at 554 nm, and is spectrally similar to Cy®3 (GE Healthcare), TRITC, iFluor® 514 (ATT Bioquest) and iFluor® 546 (ATT Bioquest). Many flow cytometers are equipped with 532nm lasers, so while Alexa 532 can be used for flow cytometry, PE is more commonly used due to its brightness and spectral characteristics. This dye is commonly used for fluorescence microscopy applications.
