Intra-assay Precision (Precision within an assay): CV%<8%
Three samples of known concentration were tested twenty times on one plate to assess.
Inter-assay Precision (Precision between assays): CV%<10%
Three samples of known concentration were tested in twenty assays to assess.
To assess the linearity of the assay, samples were spiked with high concentrations of human AST in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.
The recovery of human AST spiked to levels throughout the range of the assay in various matrices was evaluated. Samples were diluted prior to assay as directed in the Sample Preparation section.
I would like to know if the kit is free of human or animal byproducts, HIV/AIDS/HCV/HBV/infectious material.
Thanks for your inquiry.The kit is developed for the human matrix to quantitatively detect the content of the corresponding protein. Some components of the kit contain BSA,there is no HIV / AIDS / HCV / HBV / infective material. All kits are for scientific research use, there is no infectious component and can be used in accordance with conventional biosecurity rules of operation.
Function (From Uniprot)
Biosynthesis of L-glutamate from L-aspartate or L-cysteine. Important regulator of levels of glutamate, the major excitatory neurotransmitter of the vertebrate central nervous system. Acts as a scavenger of glutamate in brain neuroprotection. The aspartate aminotransferase activity is involved in hepatic glucose synthesis during development and in adipocyte glyceroneogenesis. Using L-cysteine as substrate, regulates levels of mercaptopyruvate, an important source of hydrogen sulfide. Mercaptopyruvate is converted into H(2)S via the action of 3-mercaptopyruvate sulfurtransferase (3MST). Hydrogen sulfide is an important synaptic modulator and neuroprotectant in the brain.
