About IRS-1
This gene encodes a member of the Iroquois homeobox protein family. Homeobox genes in this family are involved in pattern formation in the embryo. The gene product has been identified as a tumor suppressor in gastric (PMID: 21602894, 20440264) and head and neck cancers (PMID: 18559491). A pseudogene of this gene is located on chromosome 13.

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.
