  • 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

CHEK2 / CHK2 antibody was raised against a synthetic peptide obtained from human Chk2 protein sequence.
A synthetic peptide obtained from human Chk2 protein sequence was used as immunogen.
Immunohistochemistry: LS-B1321 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-B1321 was determined to be 10 ug/ml.


PBS, 0.02% sodium azide.
Short term: +4°C; Long term: -70°C.

CHEK2 Antibody, BA444G7 Antibody, Cds1 homolog Antibody, Checkpoint kinase 2 Antibody, Checkpoint-like protein CHK2 Antibody, CHK2 checkpoint homolog Antibody, CHK2 Antibody, HCds1 Antibody, LFS2 Antibody, RAD53 Antibody, Rad53 homolog Antibody, HCHK2 Antibody, HuCds1 Antibody, PP1425 Antibody

Serine/threonine-protein kinase which is required for checkpoint-mediated cell cycle arrest, activation of DNA repair and apoptosis in response to the presence of DNA double-strand breaks. May also negatively regulate cell cycle progression during unperturbed cell cycles. Following activation, phosphorylates numerous effectors preferentially at the consensus sequence [L-X-R-X-X-S/T].
