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".

Specificity and Use
Nsr1p antibody was raised against nsr1p is localized in the nucleolus and binds to telomeric single-stranded oligonucleotide repeat sequence of the type and binds to the single-stranded telomeric repeat sequence (TG1-3)n. It has a role in ribosomal RNA maturation and possibly in transport
31C4 was isolated during a screen for monoclonal antibodies reactive with yeast nucleolar proteins. We determined the specificity by screening a yeast genomic library expressed as b-galactosidase fusion proteins in lgt11. Two individually isolated, different positive clones were found. Sequencing revealed that in both clones b-galactosidase was fused at the EcoRI site to the amino acid sequence beginning with EFEH, corresponding to amino acids 190 and onwards in Nsr1p. This peptide is ~20 amino acids into the first RRM domain. Thus, MCA-31C4 reacts with an epitope in the C-terminal 55% of Nsr1p. The antibody is provided as sterile-filtered cell culture fluid from an Integra CL-350 biochamber plus sodium azide. The IgG isotype and exact concentration are not known.
