特異性

Clone 8B21 is a ZooMAb^® Rabbit recombinant monoclonal antibody that specifically detects Histone H2A ubiqutinylated on lysine 119.

免疫原

KLH-conjugated linear peptide corresponding to 10 amino acids surrounding ubiquityl lysine 119 from the C-terminal region of human Histone H2A.

アプリケーション

Quality Control Testing

Evaluated by Western Blotting in HeLa cell acid extract.

Western Blotting Analysis: A 1:10,000 dilution of this antibody detected Ubiquityl-Histone H2A-Lys119 in HeLa cell acid extract.

Tested Applications

Western Blotting Analysis: A 1:10,000 dilution from a representative lot detected Ubiquityl-Histone H2A-Lys119 in acid exacts of Balb3T3/A31, HL-60, and Rat2 cells.

Peptide Inhibition Assay: Target band detection in HeLa cell acid extract was prevented by preblocking of a representative lot with the immunogen Ubiquityl-Histone H2A-Lys119 peptide.

Immunohistochemistry (Paraffin) Analysis: A 1:1,000 dilution from a representative lot detected Ubiquityl-Histone H2A-Lys119 in human testis tissue sections.

Immunocytochemistry Analysis: A 1:100 dilution from a representative lot detected Ubiquityl-Histone H2A-Lys119 in HeLa cells.

Flow Cytometry Analysis: 1 µg from a representative lot detected Ubiquityl-Histone H2A-Lys119 in one million NIH3T3 cells.

Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user.

ターゲットの説明

Histone H2A type 1-A (UniProt: Q96QV6; also known as H2A-clustered histone 1, Histone H2A/r) is encoded by the H2AC1 (also known as H2AFR, HIST1H2AA) gene (Gene ID:  221613) in human. Histones are highly conserved basic nuclear proteins that are responsible for the nucleosome structure of chromatin in eukaryotes. They 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. 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 that require DNA as a template. Histones are modified post-translationally by acetylation, phosphorylation, methylation, and ubiquitination and these modifications regulate DNA transcription, repair, recombination, and replication. Ubiquitylation usually targets the substrate for degradation, although histones H2A and H2B are actually stabilized by a single ubiquitin conjugation. Histone ubiquitination has been correlated with DNA repair and transcription, cellular differentiation, cell cycle regulation, spermatogenesis, protein trafficking, and response to stress. Histone H2A is involved in the structure of chromatin in eukaryotic cells. It features a main globular domain and a long N-terminal tail H2A. Monoubiquitination of lysine 119 (H2AK119Ub) by RING1, TRIM37 and RNF2/RING2 complex, a highly conserved modification, gives a specific tag for epigenetic transcriptional repression and participates in X chromosome inactivation of female mammals. It is involved in the initiation of both imprinted and random X inactivation. Ubiquitinated H2A is reported to be enriched in inactive X chromosome chromatin. H2AK119Ub is also reported to play a role in spermatogenesis and may promote transformation of cells in a number of breast cancers. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

物理的形状

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.

保管および安定性

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.
