Descripción general

We are committed to bringing you greener alternative products, which adhere to one or more of The 12 Principles of Green Chemistry.This antibody is Preservative-free, produced without the harm or sacrifice of animals and exceptionally stable to allow for ambient shipping and storage if needed and thus aligns with "Waste Prevention", "Designing Safer Chemicals" and "Design for Energy Efficiency". Click here for more information.
ZooMAb® antibodies represent an entirely new generation of recombinant monoclonal antibodies.Each ZooMAb® antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb® antibodies are reliably available and ready to ship when you need them.

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.

Descripción de destino

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.

Forma física

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.

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.
