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".
Carbonic anhydrases (CAs) are a large family of zinc metalloenzymes that catalyze the reversible hydration of carbon dioxide. They participate in a variety of biological processes, including respiration, calcification, acid-base balance, bone resorption, and the formation of aqueous humor, cerebrospinal fluid, saliva, and gastric acid. They show extensive diversity in tissue distribution and in their subcellular localization.
Carbonic Anhydrase IX/CA9 in Human Colon Cancer Tissue. Carbonic Anhydrase IX/CA9 was detected in immersion fixed paraffin-embedded sections of human colon cancer tissue using Goat Anti-Human Carbonic Anhydrase IX/CA9 Antigen Affinity-purified Polyclonal Antibody at 15 ug/ml overnight at 4°C. Tissue was stained using Anti-Goat HRP-DAB (brown) and counterstained with hematoxylin (blue). Specific labeling was localized to the plasma membrane of epithelial cells.
Detection of Human Carbonic Anhydrase IX/CA9 by Western Blot. Western blot shows lysates of U-87 MG human glioblastoma/ astrocytoma cell line. PVDF membrane was probed with 1 ug/ml of Goat Anti-Human Carbonic Anhydrase IX/CA9 Antigen Affinity-purified Polyclonal Antibody followed by HRP-conjugated Anti-Goat IgG Secondary Antibody. A specific band was detected for Carbonic Anhydrase IX/CA9 at approximately 58 kD (as indicated). This experiment was conducted under reducing conditions.
