Adenosine triphosphate/Adenosine diphosphate [Entitic molar ratio] in Platelets

Active

Term Description

Adenosine diphosphate (ADP) and adenosine triphosphate (ATP) is extracted from platelets. The submitter's lab performs a 2 step reaction to measure ATP and ADP (after conversion to ATP). The ADP/ATP ratio is then determined.

ADP: 1.7 - 3.8 umol / 10^11 platelets ATP: 3.1 - 7.0 umol / 10^11 platelets ratio ATP/ADP <2.0 (dimensionless)

Part Descriptions

LP14737-8   Adenosine triphosphate
Adenosine-5'-triphosphate (ATP) is a multifunctional nucleotide used in cells as a coenzyme. It is often called the "molecular unit of currency" of intracellular energy transfer. ATP transports chemical energy within cells for metabolism. It is produced by photophosphorylation and cellular respiration and used by enzymes and structural proteins in many cellular processes, including biosynthetic reactions, motility, and cell division. One molecule of ATP contains three phosphate groups, and it is produced by ATP synthase from inorganic phosphate and adenosine diphosphate (ADP) or adenosine monophosphate (AMP). Metabolic processes that use ATP as an energy source convert it back into its precursors. ATP is therefore continuously recycled in organisms: the human body, which on average contains only 250 grams (8.8 oz) of ATP, turns over its own body weight in ATP each day. ATP is used as a substrate in signal transduction pathways by kinases that phosphorylate proteins and lipids, as well as by adenylate cyclase, which uses ATP to produce the second messenger molecule cyclic AMP.

LP14737-8   Adenosine triphosphate
The amount of adenosinetriphosphate (ATP) present in stimulated (usually PHA) blood specimens is a measure of lymphocyte activity. Normal range (226-524 ng/mL). CD4 lymphocytes orchestrate CMI responses through immunoregulatory signaling, the measurement of CD4 activation reflects the degree of immune cell function.
