Cross-validation of L-Serine ELISA and LC/MS data in human plasma samples

Ser was quantified in human plasma samples from 40 healthy subjects using IS-I-1200 ELISA kit or by LC/MS. Correlation study showed R2=0.957, thereby confirming the accuracy of the immunoassay.

L-Serine ELISA kit

Ref: IS-I-1200

L-Serine (L-Ser) is a non-essential amino acid which becomes conditionally essential - in certain circumstances - particularly when it cannot be synthesized in a sufficient amount to meet the cellular demands. L-Ser may be derived from different sources including dietary intake, the glycolytic intermediate 3-phosphoglycerate, glycine as well as protein and phospholipid degradation. It’s worth noting that enzymes involved in L-Ser biosynthesis are upregulated in highly proliferating cells, including cancer cells, to limit L-Ser over-consumption. Besides its essential role in cell proliferation, L-Ser is important for brain development and functions which are especially sustained by i) altered L-Ser levels in psychiatric disorders and ii) occurrence of severe neurological abnormalities in patients with defects in L-Ser biosynthesis.
