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".

CASP4 / Caspase 4 Assay Kit

Caspase-4 Assay Kit (Colorimetric) - LS-K12

Caspase-4 Assay Kit (Colorimetric) - LS-K12

Available for shipment within the USA only
Description:
Activation of ICE-family proteases/caspases initiates apoptosis in mammalian cells. The Caspase-4 Colorimetric Assay Kit provides a simple and convenient means for assaying the activity of caspases that recognize the sequence LEVD. The assay is based on spectrophotometric detection of the chromophore p-nitroanilide (pNA) after cleavage from the labeled substrate LEVD-pNA. The pNA light emission can be quantified using a spectrophotometer or a microtiter plate reader at 400- or 405 nm.

Type
Detection/Quantition
Usage
This assay provides for the detection of early/middle stages of apoptosis; differentiate apoptosis from necrosis. Comparison of the absorbance of pNA from an apoptotic sample with an uninduced control allows determination of the fold increase in LEVD-dependent Caspase activity.
