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".
Human (tested or 100% immunogen sequence identity)
Specificity and Use
Pooled immunoglobulin-depleted human serum and partly purified serum fractions
In immunoelectrophoresis against pooled serum and enriched serum proteins fractions precipitation can be observed of not less than 15 individual proteins components.Inter-species cross-reactivity is a normal feature of antibodies to animal proteins since homologous proteins of different species frequently share antigenic determinants. Not species-specific. Sufficient positively charged ions will optimize the resolution of the proteins in the beta-gamma regions, while the alpha regions will become more dense. Highly purified agar with low electroendosmosis favours the resolution of the proteins in the alpha regions, while the major components in the beta-gamma region can still be identified.
Reconstitute the lyophilized antiserum by adding 1 ml sterile distilled water. Dilutions may be prepared by adding phosphate buffered saline (PBS, pH 7.2). In immunoelectrophoresis use 2 µl serum or equivalent against 120 µl antiserum. In double radial immunodiffusion use a rosette arrangement with 10 µl antiserum in 3 mm diameter center well and 2 µl serum samples (neat and serially diluted in 2 mm diameter peripheral wells.
No preservative added.
Short term 4°C, long term aliquot and store at -20°C, avoid freeze thaw cycles. Store undiluted.
