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".

The extracellular domain of mouse IL-4 (aa 21-140) is fused to the N-terminus of the Fc region of a mutant mouse IgG2a.
aa 21-140
CHO Cells
Hamster-Chinese
Mouse mutant IgG2a Fc
Greater than 98% by SDS-PAGE
Shows the biological function of the IL-4 moiety and exerts a prolonged circulating half-life caused by the modified Fc domain.
Less than 0.06 EU/µg protein (determined by LAL method).
Lyophilized from PBS.
Store lyophilized at -20°C for at least 1 year. Once reconstituted store at +4°C for immediate use, or aliquot and store at -20°C for up to 3 months. Avoid repeat freeze-thaw cycles.
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.
