TAR DNA Binding Protein 43 (TARDBP, TDP-43, TDP43)

Cat no: T1019-47A

TAR DNA Binding Protein 43 (TARDBP, TDP-43, TDP43)

HIV-1, the viral cause of acquired immunodeficiency syndrome (AIDS), contains an RNA genome that produces a chromosomally integrated DNA during the replicative cycle. Activation of HIV-1 gene expression, by the transactivator Tat, is dependent on an RNA regulatory element (TAR) located downstream of the transcription initiation site. TARDBP is a transcriptional repressor that binds to chromosomally integrated TAR DNA and represses HIV-1 transcription. Recently it has been shown that TDP-43 accumulates abnormally in post-mortem brain tissue from individuals diagnosed with both ALS (Amyotrophic Lateral Sclerosis) and FTD (Frontal Temporal Dementia). This observation provides a long sought connection between two disease that often over-lap clinically.\n\nApplications: \nSuitable for use in Western Blot, Immunohistochemistry and Immunofluorescence/Immunocytochemistry. Other applications not tested.\n\nRecommended Dilutions:\nWestern Blot: 0.5-2ug/ml\nImmunofluorescence/Immunocytochemistry: 1:100-1:1000. A nuclear signal is present in MCF-7 cells.\nOptimal dilutions to be determined by the researcher.\n\nPositive Control: \nHela Whole Cell Extract\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Aliquots are stable for 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
