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 CBS in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

Target Background

(From Uniprot)
Hydro-lyase catalyzing the first step of the transsulfuration pathway, where the hydroxyl group of L-serine is displaced by L-homocysteine in a beta-replacement reaction to form L-cystathionine, the precursor of L-cysteine. This catabolic route allows the elimination of L-methionine and the toxic metabolite L-homocysteine. Also involved in the production of hydrogen sulfide, a gasotransmitter with signaling and cytoprotective effects on neurons.
Involvement in disease Cystathionine beta-synthase deficiency (CBSD)
Subcellular Location Cytoplasm. Nucleus.
Protein Families Cysteine synthase/cystathionine beta-synthase family
Tissue Specificity In the adult strongly expressed in liver and pancreas, some expression in heart and brain, weak expression in lung and kidney. In the fetus, expressed in brain, liver and kidney.
