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.

Host cell factor 1 (UniProt: P51610; also known as HCF, HCF-1, C1 factor, CFF, VCAF, VP16 accessory protein) is encoded by the HCFC1 (also known as HCF1, HFC1) gene (Gene ID: 3054) in human. HCF-1, a cellular transcription factor and co-activator that is required for progression through the G1 phase of the cell cycle. It is a heterodimeric complex that contains six N-terminal and six C-terminal chains that remain tightly associated in a non-covalent manner. It also contains eight HCF repeats that are specific proteolytic cleavage signals. This complex is proteolytically cleaved into one or several PPCE THET sites within the HCF repeats. HCF-1 does not bind to DNA directly, however, both N- and C-terminal chains are shown to associate with DNA. The Kelch domains in the N-terminal region recognize and associate with HCF-binding motif present in many sequence-specific DNA-binding factors. HCF-1 is reported to act in concert with E2F1 to activate transcription of S phase genes. It recruits KMT2E/MLL5 to E2F1 responsive promoters that facilitate transcriptional activation and G1 to S phase transition. HCF-1 is highly expressed in fetal tissues and the adult kidney. However, its expression is reported in many tested tissues. Mutations in HCFC1 gene have been linked to X-linked 3 mental retardation. In addition, a single point mutation in the Kelch domain (P134S) is reported to cause a temperature-induced cell-proliferation arrest and cytokinesis defects. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

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.
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.
Storage and Stability
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.
