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".
The CLCN family of voltage-dependent chloride channel genes comprises nine members (CLCN1-7, Ka and Kb) which demonstrate quite diverse functional characteristics while sharing significant sequence homology. Chloride channel 4 has an evolutionary conserved CpG island and is conserved in both mouse and hamster. This gene is mapped in close proximity to APXL (Apical protein Xenopus laevis-like) and OA1 (Ocular albinism type I), which are both located on the human X chromosome at band p22.3.
Retinae were collected from adult White Leghorn chicken and fixed in the eyecup for two hours in 4% Paraformaldehyde (in PBS). Retinae were then removed from the eyecups and incubated in 30% sucrose (in PBS) overnight. Retinal tissue was embedded and frozen in OCT compound and cut into ~15um sections on a cryotome. Sections were blocked in 5% normal goat serum (in 1%BSA/.1%saponin PBS) for one hour and then incubated at RT with 1:250 (1%BSA/.1% saponin PBS) ClC4 antibody for 1 hour. Sections were then washed in PBS (3X10minutes) and then treated with secondary antibody (1:500 Cy3) for one hour. After another PBS wash series, sections were coverslipped and antibody labeling was visualized at 20X with a Leica upright microscope using a TRITC filter set and Xenon LAMP illumination.
