Description Clone REA140 recognizes PAX-5, which belongs to the paired box (PAX) gene family of transcription factors. PAX-5 is the only mammalian PAX transcription factor, which is expressed in hematopoietic cells. Within the hematopoietic cells, expression of PAX-5 is limited to cells of the B-lymphocyte lineage and it exerts transcriptional control of B cell commitment, development, and tumorigenesis. PAX-5 contains DNA binding conserved ‘paired’ domain, which consists of an N- and a C-terminal subdomain. Each subregion contains a homeodomain-like helix-turn-helix motif, which binds to a half-site of the PAX-5 recognition sequence. Depending upon the interaction partners, PAX-5 serves either as an activator or repressor of transcription. For instance, Groucho protein family members, by binding to a conserved octapeptide motif of PAX-5, enable PAX-5 to serve as a repressor. | Additional information: Clone REA140 displays negligible binding to Fc receptors. |
About Pax5 and PerCP-Vio700
Pax5 This gene encodes a member of the paired box (PAX) family of transcription factors. The central feature of this gene family is a novel, highly conserved DNA-binding motif, known as the paired box. Paired box transcription factors are important regulators in early development, and alterations in the expression of their genes are thought to contribute to neoplastic transformation. This gene encodes the B-cell lineage specific activator protein that is expressed at early, but not late stages of B-cell differentiation. Its expression has also been detected in developing CNS and testis and so the encoded protein may also play a role in neural development and spermatogenesis. This gene is located at 9p13, which is involved in t(9;14)(p13;q32) translocations recurring in small lymphocytic lymphomas of the plasmacytoid subtype, and in derived large-cell lymphomas. This translocation brings the potent E-mu enhancer of the IgH gene into close proximity of the PAX5 promoter, suggesting that the deregulation of transcription of this gene contributes to the pathogenesis of these lymphomas. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jul 2013]
PerCP-Vio700 PerCP-Vio® 770 is a far-red-emitting tandem fluorophore that combines PerCP and a Vio®770 dye. The donor, PerCP, can be excited by the 488 nm blue laser and transfers energy to the acceptor, Vio®770, which emits light that can be captured with a 780/60 nm bandpass filter. APC-Vio®770 has an excitation peak at 482 nm and an emission peak at 704 nm, and is spectrally similar to PerCP-Cy5.5 and PerCP-eF710. PerCP-Vio®770 is known to be very bright and photostable, as well as being stable when treated with fixatives. These favorable characteristics that make it useful in multiple different applications such as flow cytometry and Fluorescence Microscopy. The large stokes shift can be advantageous when trying to fit more colors into a multicolor panel. The Vio® dye family are products of Miltenyi Biotec, with many antibody conjugates designed and validated for flow cytometry.
