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
MAP2K4 / MKK4 antibody was raised against synthetic phosphopeptide (KLH coupled) corresponding to residues around Thr261 of human SEK1.
Detects endogenous levels of human SEK1/ MKK4 protein only when phosphorylated at threonine 261. Does not cross-react with the corresponding phosphorylated residues of MEK1, MEK2 or MKK3. Species cross-reactivity: Mouse and rat.
Western Blot: 1:2000, incubate membrane with diluted antibody in 5% BSA, 1X TBS, 0.1% Tween-20 at 4?C with gentle shaking, overnight.
10 mM HEPES, pH 7.5, 150 mM sodium chloride, 0.1 mg/ml BSA, 50% glycerol. No preservative added.
Short term: 4°C. Long term: Store at -20°C. Avoid freeze-thaw cycles.
Dual specificity protein kinase which acts as an essential component of the MAP kinase signal transduction pathway. Essential component of the stress-activated protein kinase/c-Jun N-terminal kinase (SAP/JNK) signaling pathway. With MAP2K7/MKK7, is the one of the only known kinase to directly activate the stress-activated protein kinase/c-Jun N-terminal kinases MAPK8/JNK1, MAPK9/JNK2 and MAPK10/JNK3.
