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".
Purified / Lyophilized / Endotoxin Level: Less than 1.0 EU/µg protein (determined by LAL method).
IFN Beta / Interferon Beta
Greater than 98% by SDS-PAGE and HPLC
Biologically active when compared to standard. The specific activity as determined in a viral resistance assay (human "Wish" cell line and VSV virus or the monkey VERO cell line with EMCV virus) was found to be 32 x 106 IU/ mg.
Less than 0.1 ng/µg of protein.
Lyophilized from 50 mg human albumin, 50 mg dextrose
Reconstitute in water to 0.1-1.0 mg/ml. The solution can then be diluted into other aqueous buffers and stored at 4°C for 1 week or -20°C for future use.
Interferon beta (IFNB1), acting via STAT1 and STAT2, upregulates and downregulates a wide variety of genes, most of which are involved in the antiviral immune response. Most IFN responses are induced by the presence of dsRNA, but both DNA and RNA viruses are sensitive to the effects of IFN-beta.
