Overview
※For research purposes only with animal serum/plasma, Not for Diagnostic Use.
Introduction
Phospholipids are known as not only as major component of cell membranes but also perform vital functions within the body such as emulsification and absorption of fats or coagulation of blood.
Assay principle
Phospholipids are hydrolyzed by Phospholipase D to release hydrogen peroxide. The formed hydrogen peroxide promotes oxidative condensation of N-ethyl-N-(2-hydroxy-3-sulfopropyl)-3,5-dimethoxyaniline sodium salt（DAOS) with 4-aminoantipyrine. LabAssay™ Phospholipid is a kit to determine Phospholipid concentration in samples by measuring absorbance of a blue color which is generated by the oxidative condensation reaction.
Performance
| Sample | Serum, plasma (Mouse, Rat) |
|---|---|
| Standard curve range | 75.0 ~ 596.1 mg/dL (mg/100 mL) |
| Measurement time | Approx. 10 min. |
| Amount of sample | 2 μL |
| Measurement wavelength | 600 nm(Main), 700 nm(Sub) |

Procedure
| Test | Standard | Blank | |
|---|---|---|---|
| Chromogen reagent | 300 μL | 300 μL | 300 μL |
| Sample | Serum 2 μL | Standard solution 2 μL | － |
| Mix well and incubate at 37℃ for 5 min. Measure the absorbance at 600nm*2 of the test sample and standard solution with the blank solution as the control. | |||
