Method – Pyruvate → Lactate
Pack Size : R1: 1 x 8 ml R2: 1 x6 ml
Principle
Lactate dehydrogenase (LD or LDH) catalyzes the reduction of pyruvate by
NADH to form lactate and NAD The catalytic concentration is determined
from the rate of decrease of NADH measured at 340 nm.

Quality Control
To ensure adequate quality control, it is recommended that each batch
should include normal and an abnormal commercial reference control
serum. It should be realized that the use of quality control material
checks both instrument and reagent functions together. Factors which
might affect the performance of this test include proper instrument
function, temperature control, cleanliness of glassware and accuracy of
pipetting.
Other Details
The reagent kit should be stored at 2- 8°C and is stable till the expiry date
indicated on the label.
R, and R, are stable till expiry at 2-8°C:
The working solution (4 R, +1R,) is stable for 30 days at 2-8°C.
DO NOT FREEZE THE REAGENT. Contamination of the reagents should
be strictly avoided.
