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".
Tau promotes microtubule assembly and stability, and might be involved in the establishment and maintenance of neuronal polarity. The C-terminus binds axonal microtubules while the N-terminus binds neural plasma membrane components, suggesting that tau functions as a linker protein between both. Axonal polarity is predetermined by tau localization (in the neuronal cell) in the domain of the cell body defined by the centrosome.
Standard immunostaining protocol (red channel). The cells were also stained in green with BH7 a monoclonal antibody to Ubiquitin C-terminal Hydrolase 1 (UCHL1), an abundant cytoplasmic protein of neurons which is concentrated in the perikarya. Since the perikarya contain both UCHL1 and Tau, the red and green signals superimpose, giving a yellow color, while the processes, which contain relatively much more tau, appear red. Blue stain is DAPI and reveals cell nuclei of some non neuronal cells in these cultures.
Stripe blot of crude rat brain extract. Tau protein is expressed as up to 9 different isoforms of different molecular weight and so appears as multiple closely spaced bands covering the region of the blot from 48kDa to 67kDa, with an additional band at 100kDa.
