Glutamine ELISA kit

Glutamine (Gln) is an abundant non-essential amino acid that is involved in several physiological functions

including the regulation of the immune system (1). However, in some disease conditions, Gln metabolism

can be highly dysregulated. In cancer, Gln is highly consumed by tumor cells as to fulfill their bioenergetic

and biosynthetic requirements for proliferation (2). Targeting Gln catabolism - mainly Glutaminase - is

currently investigated as a therapeutic approach to circumvent high Glnconsumption by cancer cells and

maintain a sufficient level in the microenvironment for an effective anti-tumor immune response (3).

The IS-I-1100 Gln ELISA kit allows for the determination of L-Glutamine in plasma and serum, originating

from either preclinical or clinical samples, of a volume as low as 10μL and with a sensitivity of 3µM.

Cross-validation of Glutamine ELISA and LC/MS data in human plasma samples Gln was

quantified in human plasma samples from 40 healthy subjects using IS-I-1100 ELISA kit or by LC/MS.

Correlation study showed R2=0.9946, thereby confirming the accuracy of the immunoassay.
