Description Clone REA919 recognizes the mouse Ikaros protein, also known as DNA-binding protein Ikaros, Ikaros family zinc finger protein 1, or IKZF1. Ikaros is a transcription regulator of hematopoietic cell differentiation of lymphocytes, B cells, and T cells, and functions as a major tumor suppressor involved in human B cell acute lymphoblastic leukemia. In association with other Ikaros-family members, e.g. Aiolos and Helios, Ikaros forms heterodimers, that are important for normal progression to a mature and immunocompetent state. Ikaros is found in the nucleus to a higher extent in granulocytes, B cells, T cells, and NK cells, and in lower levels in erythroblasts, megakaryocytes, and monocytes. | Additional information: Clone REA919 displays negligible binding to Fc receptors.
About Ikaros and PE
Ikaros This gene encodes a transcription factor that belongs to the family of zinc-finger DNA-binding proteins associated with chromatin remodeling. The expression of this protein is restricted to the fetal and adult hemo-lymphopoietic system, and it functions as a regulator of lymphocyte differentiation. Several alternatively spliced transcript variants encoding different isoforms have been described for this gene. Most isoforms share a common C-terminal domain, which contains two zinc finger motifs that are required for hetero- or homo-dimerization, and for interactions with other proteins. The isoforms, however, differ in the number of N-terminal zinc finger motifs that bind DNA and in nuclear localization signal presence, resulting in members with and without DNA-binding properties. Only a few isoforms contain the requisite three or more N-terminal zinc motifs that confer high affinity binding to a specific core DNA sequence element in the promoters of target genes. The non-DNA-binding isoforms are largely found in the cytoplasm, and are thought to function as dominant-negative factors. Overexpression of some dominant-negative isoforms have been associated with B-cell malignancies, such as acute lymphoblastic leukemia (ALL). [provided by RefSeq, May 2014]
PE Phycoerythrin (PE, R-PE) is a red-emitting fluorescent protein-chromophore complex that can be excited the 488-nm blue, 532-nm green, or 561-nm yellow-green laser with increasing efficiency and captured with a 586/14 nm bandpass filter. PE has an excitation peak at 565 nm and an emission peak at 578 nm. PE is 240kD in size and has an extinction coefficient of ~2x10^6 which makes it one of the brightest fluorophores available and a potent donor upon which to build tandem fluorophores with longer Stoke's Shifts.
