Ref: IS-I-1100R
+Typical standard curve of Glutamine ELISA
Typical standard curve obtained with the Gln ELISA kit where the optical density is inversely correlated within levels within a linear range of 21 - 3125μM. (example data - do not use for calculation)
Glutamine (Gln) is an abundant non-essential amino acid that is involved in several physiological functions including the regulation of the immune system . 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. Targeting Gln catabolism – mainly Glutaminase – is currently investigated as a therapeutic approach to circumvent high Gln consumption by cancer cells and maintain a sufficient level in the microenvironment for an effective anti-tumor immune response.
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.
