  • Immunohistochemistry Services

  • Work with LifeSpan to design a custom immunohistochemistry to address your specific biological question. Outsource the entire localization process without having to worry about finding and characterizing target specific antibodies, sourcing and validating difficult-to-find tissues, and having the ability to interpret the resulting immunostaining in relation to complex human pathologies.

  • TCR Screening Services

  • Test your therapeutic antibodies in immunohistochemistry against a broad panel of normal frozen human tissue types in order to determine potential unintended binding. Our non-GLP TCR services are designed on the FDA recommendation outlined in their "Points to Consider in the Manufacture and Testing of Monoclonal Antibody Products for Human Use".

Specificity and Use

PLK1 / PLK-1 antibody was raised against synthetic peptide from human PLK1.
Modified peptide
Immunohistochemistry: LS-B1675 was validated for use in immunohistochemistry on a panel of 21 formalin-fixed, paraffin-embedded (FFPE) human tissues after heat induced antigen retrieval in pH 6.0 citrate buffer. After incubation with the primary antibody, slides were incubated with biotinylated secondary antibody, followed by alkaline phosphatase-streptavidin and chromogen. The stained slides were evaluated by a pathologist to confirm staining specificity. The optimal working concentration for LS-B1675 was determined to be 15 ug/ml.


Phosphate-buffered solution, pH 7.2, 0.09% sodium azide at 0.5 mg/ml. Sourced in TCS.
+4°C, avoid freezing
For research use only.

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.

Western blot

Western blot
Panel A. Extracts from untreated Hela cells (Lane 1) or overnight nocodazole-treated Hela cells (Lane 2) were immunoprecipitated with the pan-PLK mAb (clone 3F8), resolved by electrophoresis, transferred to nitrocellulose and probed with mAb 2A3 reactive against Thr210-phosphorylated PLK-1. Proteins were visualized using an HRP goat anti-mouse secondary Ab and a chemiluminescence detection system. Panel B. Extracts from untreated Hela cells (Lane 1) or overnight nocodazole-treated Hela cells (Lane 2) were resolved by electrophoresis, transferred to nitrocellulose and probed with mAb 2A3 reactive against Thr210-phosphorylated PLK-1. Proteins were visualized using an HRP goat anti-mouse secondary and a chemiluminescence detection system.
