  • Product overview

    In Abcam's Glutamic Oxaloacetic Transaminase Activity Assay Kit an amino group is transferred of from aspartate to alpha-ketoglutarate. The products of this reversible transamination reaction are oxaloacetate and glutamate. The glutamate is detected in a reaction that concomitantly converts a nearly colorless probe to color (λmax = 450 nm). The kit provides a rapid, simple, sensitive and reliable test suitable as a high throughput activity assay of GOT with a detection limit of 10 mU per well.

  • Notes

    Glutamate-oxaloacetate transaminase (GOT), also known as Aspartate aminotransferase (AST) is a transaminase (EC similar to the more liver specific alanine transaminase (ALT). Although commonly included clinically as part of a diagnostic liver function test, GOT has a broader clinical utility since it may also be elevated in diseases affecting other organs, such as the heart or muscles in myocardial infarction, also in acute pancreatitis, acute hemolytic anemia, severe burns, acute renal disease, musculoskeletal diseases and trauma. It catalyzes the reaction: Aspartate + alpha-Ketoglutarate = Oxaloacetate + Glutamate Diagnostically, it is almost always measured in units/liter (U/L).

    • GOT activity measured in mouse tissue lysates showing activity (mU) per mg of extracted protein (T1=2 min; T2=60 min).

    • GOT activity measured in human biological fluids showing activity (mU) per mL of tested sample, (T1=2 min; T2=60 min) with background signals subtracted.

    • GOT activity measured in cell culture medium and control medium, background signal subtracted. T1=2 min; T2=60 min.

    • GOT activity measured in cell lysates (T1=2 min; T2=60 min; duplicates (+/- SD), background signal subtracted).

    • Standard curve (60 minutes incubation): mean of duplicates (+/- SD) with background reads subtracted.

    It is recommended to measure standard curve at both times 10 mins and 60 mins. Then use the difference in Abs at 60min - Abs at 10min to plot the Std curve (OD on Y axis versus Glutamate nmol on the X axis).
