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".
Western blot, ELISA, Functional Assay, Neutralization
Mouse (tested or 100% immunogen sequence identity)
Western blot (0.1 - 0.2 µg/ml)
ELISA (0.5 µg/ml)
Neutralization (0.25 - 0.4 µg/ml)
Specificity and Use
IL4 antibody was raised against recombinant mouse IL-4.
Specific for mouse interleukin-4 (IL-4).
Suitable for use in ELISA (direct), Western Blot and Neutralization. ELISA: 0.5 ug/ml. Western Blot: 0.1-0.2 ug/ml. Neutralization: 0.25-0.40 ug/ml to yield one half maximal inhibition (ND50) of mouse IL-4.
100 µl deionized water
Long term: Add glycerol (40-50%) -20°C; Short term: +4°C
IL4 is a pleiotropic cytokine produced by activated T cells. This cytokine is a ligand for interleukin 4 receptor. The interleukin 4 receptor also binds to IL13, which may contribute to many overlapping functions of this cytokine and IL13. STAT6, a signal transducer and activator of transcription, has been shown to play a central role in mediating the immune regulatory signal of this cytokine.
