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.


Clone 1C14 is a ZooMAb® Rabbit recombinant monoclonal antibody that specifically detects Prolyl 4-hydroxylase subunit alpha-1 (P4HA1), It targets an epitope within 25 amino acids from the internal region.


KLH-conjugated linear peptide corresponding to 25 amino acids from the internal region of human Prolyl 4-hydroxylase subunit alpha-1 (P4HA1)

Target description

Prolyl 4-hydroxylase subunit alpha-1 (UniProt: P13674; also known as EC:, 4-PH alpha-1, Procollagen-proline,2-oxoglutarate-4-dioxygenase subunit alpha-1, P4HA1) is encoded by the P4HA1 (also known as P4HA) gene (Gene ID: 5033) in human. Prolyl 4-hydroxylase is a key enzyme in collagen synthesis and is composed of two identical a subunits and two b subunits. In collagen and related proteins, prolyl 4-hydroxylase is reported to catalyze the formation of 4-hydroxyproline, which is essential to the proper three-dimensional folding of newly synthesized procollagen chains. Three P4HA isoforms (P4HA1-3) have been identified in mammalian cells and P4HA1 is the major isoform described in most cell types and tissues and contributes to the majority of the prolyl 4-hydroxylase activity. It is localized in endoplasmic reticulum lumen and catalyzes the post-translational formation of 4-hydroxyproline in -Xaa-Pro-Gly- sequences in collagens and other proteins. Depletion of P4HA1 in melanoma cells is reported to reduce cell adhesion, invasion, and viability in vitro. In melanoma xenograft models, P4HA1 knockdown reduces melanoma tumor invasion and the deposition of collagens, particularly type IV collagen, in the interstitial extracellular matrix and in the basement membranes of tumor blood vessels. This can lead to vessel wall rupture and hemorrhages. Significantly higher levels of P4HA1 are reported in subjects with lung adenocarcinomas and relate to worse overall survival. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

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.


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.
