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 / Biologically Active / Endotoxin Level: Less than 0.2 ng/µg of protein.
Greater than 98% by SDS-PAGE and HPLC
The ED50 as determined by the dose-dependent stimulation of the proliferation of murine T11 cells is <=2.0 ng/ml, corresponding to a specific activity of >=5 x 10^5 units/mg.
Less than 0.01 ng/µg of protein (Less than 0.1 EU/µg).
Lyophilized. No additives.
Centrifuge the vial before opening. Reconstitute in water to 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week.
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 freeze-thaw cycles.
Cytokine that stimulates the proliferation of hematopoietic stem cells and megakaryocyte progenitor cells and induces megakaryocyte maturation resulting in increased platelet production (PubMed:2145578). Also promotes the proliferation of hepatocytes in response to liver damage. Binding to its receptor formed by IL6ST and either IL11RA1 or IL11RA2 activates a signaling cascade that promotes cell proliferation (PubMed:12919066).
