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.
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".

STAT5B antibody was raised against amino acids 774-787 of human STAT5B (GRPMDSQWIPHAQS). The peptide was coupled to KLH prior to immunization. Percent identity by BLAST analysis: Human, Gorilla, Gibbon, Mouse, Rat, Hamster, Elephant, Dog, Bovine, Horse, Pig (100%); Panda, Bat, Chicken, Xenopus (93%); Opossum (86%).
Recognizes the 90-92kD forms of STAT5B protein. Species cross-reactivity: Human and mouse.
Western Blot: 0.5-2 mg/ml detects STAT5B (doublet of 90kD and 92kD) in. human A431 and mouse 3T3 fibroblasts using enhanced chemiluminescence with a five minute exposure. Immunoprecipitation: 4 ug immunoprecipitates STAT5B from A431 carcinoma cells and a. previous lot immunoprecipitated STAT5B from human Raji cells. A RIPA lysate of human A431 cells (500 ug protein) was incubated with 4 ug of anti-STAT 5B Immune complexes were precipitated with protein A agarose and analyzed by immunoblotting with anti- STAT 5B. Bands were visualized using a goat anti-rabbit IgG secondary antibody conjugated to HRP in conjunction with enhanced chemiluminescence detection. Positive Antigen Control: mouse 3T3 cell lysate. Add 2.5 ul of 2-mercaptoethanol. per 100 ul of lysate and boil for 5 minutes to reduce the preparation. Load 20 ug of reduced lysate per lane for minigels.
Supplied as a liquid in 0.1 M Tris-glycine, pH 7.4, 0.15 M sodium chloride, 0.05% sodium azide.
Short term: 4°C; Long term: Add glycerol (40-50%) -20°C.
STAT5B is a member of the STAT family of transcription factors. In response to cytokines and growth factors, STAT family members are phosphorylated by the receptor associated kinases, and then form homo- or heterodimers that translocate to the cell nucleus where they act as transcription activators. This protein mediates the signal transduction triggered by various cell ligands, such as IL2, IL4, CSF1, and different growth hormones.
