Opis

General description

Histone acetyltransferase p300 (UniProt: Q09472; also known as EC:2.3.1.48, p300 HAT, E1A-associated protein p300, Histone butyryltransferase p300, Histone crotonyltransferase p300, Protein 2-hydroxyisobutyryltransferase p300, Protein propionyltransferase p300) is encoded by the EP300 (also known as P300) gene (Gene ID: 2033) in human. p300 serves as a transcriptional co-activator protein that plays a central role in coordinating and integrating multiple signal-dependent transcriptional events, such as cell proliferation, differentiation, and apoptosis. It has histone acetyltransferase (HAT) activity that transfers an acetyl group to the -amino group of multiple lysine residues. p300 localizes to active chromatin and acetylates all four core histones in nucleosomes, providing an epigenetic tag for transcriptional activation. It also shown to mediate cAMP-gene regulation by binding specifically to phosphorylated CREB protein. It mediates acetylation of histone H3 at lysine 122, a modification that localizes at the surface of the histone octamer and stimulates transcription, possibly by promoting nucleosome instability. It also mediates acetylation of histone H3 at lysine 27. It can also acetylase a number of non-histone targets, such as ALX1, HDAC1, PRMT1 or SIRT2. Its acetylation of HDAC1 is shown to lead to inactivation and modulation of transcription. p300 contains one TAZ-type 1 (aa 331-417), one TAZ-type 2 (aa 1728-1809), and one ZZ-type (aa 1664-1707) zinc finger domains. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Anti-p300, clone 4E5 ZooMAb^®, Cat. No. ZRB1204, is a recombinant Rabbit monoclonal antibody that detects p300 (Histone Acetyltransferase p300) and is tested for use Affinity Binding Assay, ELISA, Immunocytochemistry, and Western Blotting.

Biochem/physiol Actions

Clone 4E5 a ZooMAb^® Rabbit recombinant monoclonal antibody that detects Histone acetyltransferase p300. It targets an epitope within the N-terminal half.

Physical form

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 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.

Preparation Note

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.

Reconstitute lyophilized antibody pellet with 25μL of ultrapure water or Phosphate Buffered Saline (PBS). Please refer to our reconstitution protocol and the specific application guidance on the suggested starting dilutions and sample type.
