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)
IgM Monoclonal [6-13-19-1]
IHC - Paraffin (1:50)
Cytotoxic Assay (1:5)
Specificity and Use
CD57 / HNK1 antibody was raised against jURKAT T-cell line
Reacts with a 110 kD antigen present on the peripheral blood lymphocyte subset (primarily large granular lymphocytes) identified by the HNK-1 monoclonal antibody. It recognizes part of the Natural Killer cell population. CD57 is furthermore present on cells in neuroectodermal tissue. Positive control: peripheral bloodlymphocytes.
Dilution in phosphate buffered saline containing 1% BSA and 0.02% sodium azide is appropriate.
Ascites (no preservative).
Short term 4°C, long term aliquot and store at -20°C, avoid freeze thaw cycles. Store undiluted.
Involved in the biosynthesis of L2/HNK-1 carbohydrate epitope on glycoproteins. Can also play a role in glycosaminoglycan biosynthesis. Substrates include asialo-orosomucoid (ASOR), asialo-fetuin, and asialo-neural cell adhesion molecule. Requires sphingomyelin for activity: stearoyl-sphingomyelin was the most effective, followed by palmitoyl-sphingomyelin and lignoceroyl-sphingomyelin.
