TIA-1 (T-cell intracytoplasmic antigen) monoclonal antibody reacts with a 15 kDa cytoplasmic granule-associated protein, expressed in lymphocytes processing cytolytic potential. The expression of TIA-1 was studied in CD30+ anaplastic large cell lymphomas (ALCL), NK cell lymphomas and peripheral T-cell lymphomas and T cell lymphocytosis, B-cell lymphomas and lymphoblastic leukemia, Hodgkin’s etc. Studies showed that 60 to 70% of anaplastic large cell lymphoma reacted with TIA-1. Studies also indicate that TIA-1 reacts with most large granular lymphocytic leukemia’s, hepatosplenic T-cell lymphomas, intestinal T-cell lymphomas, NK-like T-cell lymphomas, NK-cell lymphomas, nasal T/NK-cell lymphomas, subcutaneous T-cell lymphomas, pulmonary angiocentric lymphomas of T or NK phenotype. The author’s concluded from TIA-1 studies that anaplastic large-cell lymphomas are cytotoxic T-or NK-cell neoplasms. All B-cell lymphomas, Hodgkin’s and lymphoblastic leukemias were negative for TIA-1.
Our Abpromise guarantee covers the use of ab2712 in the following tested applications.
|IHC-P||1/50 - 1/100. Incubate for 30-60 minutes at RT. Use heat-mediated antigen retrieval, an optional pepsin treatment can also improve the signal.|
Human normal spleen. Staining is observed in the cytoplasm. Left panel: with primary antibody at 1 ug/ml. Right panel: isotype control. Sections were stained using an automated system at room temperature: sections were rehydrated and antigen retrieved with buffers citrate EDTA pH 9.0. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 minutes. They were then blocked for 10 minutes (casein 0.25% in PBS) then incubated with primary antibody for 20 minutes. Colorimetric detection was completed with Diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin and coverslipped. Please note that for manual staining we recommend to optimize the primary antibody concentration and incubation time (overnight incubation), and amplification may be required.
