Anti-PLK1 Antibody, clone 1F2 ZooMAb^® Rabbit Monoclonal

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.

Clone 1F2 is a ZooMAb^® rabbit recombinant monoclonal antibody that specifically detects Polo-like Kinase 1 (PLK1). It targets an epitope within 22 amino acids from the C-terminal half.

Serine/threonine-protein kinase PLK1 (UniProt: P53350; also known as EC: 2.7.11.21, Polo-like kinase 1, PLK-1, Serine/threonine-protein kinase 13, STPK13) is encoded by the PLK1 (also known as PLK) gene (Gene ID: 5347) in human. PLK-1 is a serine/threonine-protein kinase that performs several important functions throughout M phase of the cell cycle, including the regulation of centrosome maturation and spindle assembly, the removal of cohesins from chromosome arms, the inactivation of anaphase-promoting complex/cyclosome (APC/C) inhibitors, and the regulation of mitotic exit and cytokinesis. Its expression is observed in placenta and colon and its activity is enhanced by growth promoting agents. PLK-1 is activated by phosphorylation at Thr210 by Aurora^™ kinase A.  It accumulates to a maximum during the G2 and M phases and declines to a nearly undetectable levels following mitosis and throughout G1 phase. However, it begins to accumulate again during the S phase of cell cycle. The kinase domain of PLK-1 is localized to amino acids 53-305 with activation loop in the region of amino acids 194-221. PLK-1 contains 2 POLO box domains (aa 417-480 and 515-584), which ACT^® as phosphopeptide-binding module that recognize and bind serine-phosphothreonine/ phosphoserine]-(Proline^®/X) motifs. PLK-1 recognizes and binds docking proteins that are already phosphorylated on these motifs, and then phosphorylates them.  Defects in PLK1 gene are associated with some cancers, such as gastric, thyroid or B-cell lymphomas. Expression is shown to be higher in tumor tissues with a poor prognosis, suggesting its role in malignant transformations and carcinogenesis. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, Affinity^™, reproducibility, and stability over conventional monoclonals.

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.

KLH-conjugated linear peptide corresponding to 22 amino acids from the C-terminal half of human Polo-like Kinase 1 (PLK1).

Concentration: Please refer to the Certificate of Analysis for the lot-specific concentration.

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.
