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.

Specificity

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.

Immunogen

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

Application

Quality Control Testing

Evaluated by Western Blotting in HEK293 cell lysate.

Western Blotting Analysis: A 1:1,000 dilution of this antibody detected PLK1 in HEK293 cell lysate.

Tested Applications

Western Blotting Analysis: A 1:10,000 dilution from a representative lot detected PLK1 in lysate from PC12 cells and His-tagged, full-length recombinant Human PLK1; and 1:1,000 dilution detected PLK1 in lysates from NIH3T3, and HeLa cells.

Affinity Binding Assay: A representative lot of this antibody bound His-tagged, full-length, recombinant Human PLK1 with a KD of 7.0 x 10-9 in an affinity binding assay.

Enzyme Immunoassay (ELISA) Analysis: A serial of dilutions from a representative lot detected His-tagged, full-length recombinant Human PLK1.

Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user.

Target description

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.

Physical form

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.

Reconstitution

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.

Other Notes

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