Target description

RE1-silencing transcription factor (UniProt: Q13127; also known as REST, Neural-restrictive silencer factor, X2 box repressor) is encoded by the REST (also known as NRSF, XBR) gene (Gene ID: 5978) in human. REST is a transcriptional repressor that acts by binding a DNA sequence element called the neuron-restrictive silencer element (NRSE). It is ubiquitously expressed, and higher expression is found in the tissues of the lymphocytic compartment, including spleen, thymus, peripheral blood lymphocytes, and ovary. It is also found in undifferentiated neuronal progenitor cells and it is believed that it acts as a master negative regular of neurogenesis. Expression of REST is reported to be cell cycle-dependent with reduced levels in the G2 phase. REST restricts the expression of neuronal genes by associating with two distinct corepressors, SIN3A and RCOR1, which in turn recruit histone deacetylase to the promoters of REST-regulated genes. REST also mediates repression by recruiting the BHC complex at RE1/NRSE sites, which acts by deacetylating and demethylating specific sites on histones and acting as a chromatin modifier. REST is shown to contain nine zinc finger domains, but a C-terminally truncated form is also produced by alternative splicing. Mutations in REST gene can lead to Wilms tumors, a pediatric malignancy of the kidney that occurs due to uncontrolled multiplication of renal stem, stromal, and epithelial cells. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals

Physical form

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.

Reconstitution

0.3 mg/mL after reconstitution at 25 μL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Storage and Stability

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
