一般描述
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.

目标描述
Transcription factor E2F1 (UniProt: Q01094; also known as E2F-1, PBR3, Retinoblastoma-associated protein 1, RBAP-1, Retinoblastoma-binding protein 3, RBBP-3, pRB-binding protein E2F-1) is encoded by the E2F1 (also known as RBBP3) gene (Gene ID: 1869) in human. E2F-1 is a transcription activator that binds DNA cooperatively with DP proteins through the E2 recognition site, 5′-TTTC[CG]CGC-3′ found in the promoter region of a number of genes whose products are involved in cell cycle regulation or in DNA replication. It is a component of the DRTF1/E2F transcription factor complex and forms heterodimers with DP family members. The DRTF1/E2F complex functions in the control of cell-cycle progression from G1 to S phase. The E2F1 complex is shown to bind specifically hypophosphorylated retinoblastoma protein RB1. During the cell cycle, RB1 becomes phosphorylated in mid-to-late G1 phase and detaches from the DRTF1/E2F complex that renders E2F transcriptionally active. E2F-1 can be phosphorylated by CDK2 and cyclin A-CDK2 in the S-phase. It is also phosphorylated at serine 364 by CHEK2, which stabilizes it upon DNA damage and regulates its effect on transcription and apoptosis. Acetylation of E2F-1 by P/CAF/KAT2B is reported to stimulate its DNA-binding activity. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

外形
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.
重悬
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.
储存及稳定性
Recommend storage of lyophilized product at 2-8℃; 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℃, or -20℃ for long term storage. Avoid repeated freeze-thaws.
