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".

Western blot (1:500)
ELISA (1:1000 - 1:5000)
Specificity and Use
Recombinant yeast Hub1 protein.
This purified polyclonal antibody reacts with yeast Hub1 by western blot and ELISA. Although not tested, this antibody is likely functional in immunohistochemistry and immuno-precipitation. This antibody using the specified conditions may recognize other prominent intrinsic bands (UBLs or conjugates). Other intrinsic bands are readily detectable at lower dilutions. A 9.7 kD band corresponding to yeast Hub1 is detected. Most yeast cell lysates can be used as a positive control without induction or stimulation.

Anti-Hub1 Antibody - Western Blot. Western blut of Hub1 fusion protein. Anti-Hub1 antibody generated by immunization with recombinant yeast Hub1 was tested by western blot against yeast lysates expressing the Hub1-GFP fusion protein and other UBL fusion proteins. All UBLs possess limited homology to Ubiquitin and to each other, therefore it is important to know the degree of reactivity of each antibody against each UBL. Panel A shows total protein staining using ponceau. Panel B shows positions of free GFP or GFP containing recombinant proteins present in each lysate preparation after reaction with a 1:1000 dilution of anti-GFP (code # followed by reaction with a 1:15000 dilution of HRP Donkey-a-Goat IgG MX (code # LS-C60367). Panel C shows specific reaction with Hub1 using a 1:500 dilution of IgG fraction of Rabbit-anti-Hub1 (Yeast) followed by reaction with a 1:15000 dilution of HRP Goat-a-Rabbit IgG MX (code # LS-C60865). All primary antibodies were diluted in TTBS buffer supplemented with 5% non-fat milk and incubated with the membranes overnight at 4° C. Yeast lysate proteins were separated by SDS-PAGE using a 15% gel. This data indicates that anti-Hub1 is highly specific and does not cross react with other UBLs. A chemiluminescence system was used for signal detection (Roche). Other detection systems will yield similar results. Data contributed by M. Malakhov, www. lifesensors. com, personal communication.
