Human Alpha Tocopherol Transfer Protein (TTPa) ELISA Kit

The alpha-tocopherol transfer protein (α-TTP, encoded by TTPA) is a cytosolic carrier responsible for moving vitamin E between intracellular membranes and for secreting α-tocopherol from hepatocytes into circulating lipoproteins, making it central to studies of lipid metabolism, oxidative stress, and conditions ranging from ataxia with vitamin E deficiency (AVED) to non-alcoholic fatty liver disease. This microplate-based immunoassay from Assay Genie is configured for quantitative measurement of human TTPa in research samples, with the kit supporting up to 96 determinations in a single microplate run when used according to the included protocol. Intended for in vitro research use only, the assay accommodates tissue homogenates and other sample matrices, and the kit reagents should be stored refrigerated at 4 °C between uses to preserve activity. Researchers investigating hepatic vitamin E handling, lipoprotein biology, neurodegeneration models, or comparative analysis of TTPa expression in patient-derived tissues will find this kit useful, with absorbance read on a standard plate reader. Each pack contains the microplate, reference standards, detection antibody, and ancillary buffers required to perform the full workflow, with sample wells typically prepared in 100 ul working volumes.
