CHRONO-LOG® Platelet Function Reagents

Provide High Accuracy and Low Costs Per Test

Chrono-log offers a complete line of highly concentrated platelet aggregation reagents, requiring only micro-portions per test. The standard aggregation reagents: Thrombin, ADP, Collagen, Ristocetin, Epinephrine and Arachidonic Acid are available, as well as CHRONO-LUME® and ATP Standard reagents for determination of dense granule release when performing Lumi Aggregation.

Please review this year-long study which confirmed the exceptional stability of Chrono-log aggregation reagents.

CHRONO-LOG® CHRONO-PAR® Reagents are validated for use in both Whole Blood and PRP samples.

ADP

Collagen

Each vial contains 1mg of native Collagen fibrils (type I) from equine tendons suspended in isotonic glucose solution of pH 2.7. Performs 500 to 1000 tests in PRP or Whole Blood samples.

Ristocetin

Arachidonic Acid

Epinephrine

Thrombin

CHRONO-LUME® Reagents

For Performing Secretion Study Simultaneously with Aggregation

Reagent for measurement of ATP release. Each vial contains 0.2 mg luciferin, 22,000 units d-luciferase plus magnesium sulfate, human serum albumin, stabilizers and buffer. Kit includes 4 vials of CHRONO- LUME plus a vial of lyophilized adenosine 5′ triphosphate for use as an ATP Standard. Performs 50 to 100 tests in PRP or Whole Blood samples.
