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".
25.4 kDa. DTT-reduced protein migrates as 40 kDa due to glycosylation
HEK 293 Cells
Greater than 90% by SDS-PAGE
Measured by its ability to inhibit the IL-15-dependent proliferation of MO7e human megakaryocytic leukemic cells. The ED50 for this effect is typically 0.5 - 2.5 µg/mL in the presence of 4.0 ng/mL of recombinant human IL-15.
Less than 1.0 EU/µg protein (determined by LAL method).
Lyophilized from PBS, pH 7.4, 5-8% mannitol or trehalose
Centrifuge the vial before opening. Reconstitute in sterile PBS, pH 7.4 to 50 µg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 month. For extended storage, store at -20°C.
The interleukin 2 receptor, which is involved in T cell-mediated immune responses, is present in 3 forms with respect to ability to bind interleukin 2. The low affinity form is a monomer of the alpha subunit and is not involved in signal transduction. The intermediate affinity form consists of an alpha/beta subunit heterodimer, while the high affinity form consists of an alpha/beta/gamma subunit heterotrimer.
