Services
  • 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".

Greater than 95% by SDS-PAGE and HPLC
Assay #1:Measured by its ability to induce apoptosis in HeLa cells. The expected ED50 for this effect is 20-30 ng/ml. Assay #2: Determined by a cytotoxicity assay using human TF-1 cells. The expected ED50 is = 0.1 ng/ml, corresponding to a specific activity of = 1 x 10^7 units/mg.
Less than 0.1 ng/µg of protein (less than 1EU/µg).
Sterile filtered, lyophilized from 10 mM sodium citrate, 100 mM sodium chloride, 10 mM Sucrose
Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.
If lyophilized, can be stored for 1 month at room temperature, 6 months at 4°C, or through the expiration date at -20°C to -80°C. Once reconstituted per the supplied instructions, can be stored for 3 months at -20°C to -80°C, or for 1 week at 2°C to 8°C. Avoid repeat freeze-thaw cycles.

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.
