Descripción de destino

Histone H2B (UniProt: Q8N257; also known as H2B, H2B type 12) is encoded by the HIST3H2BB gene (Gene ID: 128312) in human. Histones are basic nuclear proteins that are responsible for the nucleosome structure of chromatin in eukaryotes. Two molecules of each of the four core histones (H2A, H2B, H3, and H4) form an octamer, around which DNA is wrapped in repeating units, called nucleosomes, which limits DNA accessibility to the cellular machineries, which require DNA as a template. Histones play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. DNA accessibility is regulated via a complex set of post-translational modifications of histones, also called histone code, and nucleosome remodeling. Histone H2B is one of the main histone proteins involved in the structure of chromatin in eukaryotic cells. Featuring a main globular domain and a long N-terminal tail, H2B is involved with the structure of the nucleosomes of the ′beads on a string′ structure. Histone H2B can be monoubiquitinated on Lysine 35 by the MSL1/MSL2 dimer and this ubiquitination is reported to be essential for histone H3 lysine 4 (H3K4me) and lysine 79 (H3K79me) methylation and transcription activation at specific gene loci, such as HOXA9 and MEIS1 loci. Similarly, monoubiquitination at lysine 121(H2BK120Ub) by the RNF20/40 complex gives a specific tag for epigenetic transcriptional activation and is a prerequisite for histone H3 lysine 4 and lysine 79 methylation. Histone H2B undergoes phosphorylation at serine 37 by AMPK in response to stress and promotes transcription. During apoptosis and DNA double strand breaks it is phosphorylated on serine 15 by STK4/MST1 that facilitates apoptotic chromatin condensation. This ZooMAbZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Forma física

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS, 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.

Reconstitución

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

Almacenamiento y estabilidad

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.
