Amplite® Colorimetric Triglyceride Assay Kit Red Color

Product key features

Amplite® Colorimetric Triglyceride Assay Kit provides a sensitive and streamlined method for detecting triglycerides in diverse biological samples.

Red Colorimetric Detection: Generates a red signal measurable at 570 nm for easy absorbance quantification.
High Sensitivity: Detects as little as 20 µM triglyceride in standard sample formats.
Broad Applications: Ideal for lipid metabolism research, drug screening, and clinical triglyceride profiling.
Direct Equivalent: Replacement for Invitrogen™ Triglyceride (TG) Colorimetric Assay Kit.

Product description

Amplite® Colorimetric Triglyceride Assay Kit is a complete assay system designed for rapid and accurate quantification of triglycerides in biological samples using a red-colored detection format. The kit employs an enzymatic cascade to produce a red chromogenic product. The resulting signal is easily measured at 575 nm using a standard absorbance plate reader.

This kit supports a wide range of sample types. With its straightforward workflow, stable signal, and high sensitivity, it is ideal for lipid metabolism research, drug development, and clinical diagnostics involving triglyceride measurement.

Example protocol

AT A GLANCE

Prepare test samples along with triglyceride standards (50 μL).
Add triglyceride working solution (50 μL).
Incubate at 30-60 minutes at RT.
Monitor absorbance at 575 nm.

Important note: Thaw all the kit components at room temperature before starting the experiment.

PREPARATION OF STOCK SOLUTIONS

Unless otherwise noted, all unused stock solutions should be divided into single-use aliquots and stored at -20 °C after preparation. Avoid repeated freeze-thaw cycles

Amplite™ Red Stock Solution (100X):

Add 60 µL of DMSO (Component F) into Amplite™ Red (Component A) to make 100X Amplite™ Red stock solution.

Lipase Stock Solution (50X):

Add 110 µL ddH2O to Lipase vial (Component B) to make 50X Lipase stock solution.

PREPARATION OF STANDARD SOLUTIONS

For convenience, use the Serial Dilution Planner:

Triglyceride Standard Dilution:

To prepare the 400 µM Triglyceride Standard, mix 40 µL of Triglyceride Standard (Component E) with 460 µL of PBS. Then, create a standard curve by adding 50, 40, 30, 20, 10, 5, 2.5, or 0 µL of the 400 µM standard solution into separate wells to achieve final concentrations of 400, 320, 240, 160, 80, 40, 20, and 0 µM, respectively. Adjust each well to a total volume of 50 µL using PBS. If replicates are needed, scale the volumes proportionally to ensure consistent final concentrations across wells.

PREPARATION OF WORKING SOLUTION

Triglyceride Working Solution:

Add 5 mL Triglyceride Assay Buffer (Component D) to Enzyme Mix (Component C) and mix well. Add 100 µL of 50X Lipase Stock Solution and 50 µL of 100X Amplite™ Red Stock Solution to the bottle of Enzyme Mix.

Table 1: Preparation of 5 mL Triglyceride Working Solution

Assay Buffer (Component D)	5 mL
Enzyme Mix (Component C)	Whole bottle
50X Lipase Stock Solution	100 µL
100X Amplite™ Red Stock Solution	50 µL

Note 1: This Triglyceride working solution should be prepared freshly before the experiment, and kept away from light.
5 mL is sufficient for 100 tests.

Note 2: Alternatively, one can make a 12.5-25X of the Enzyme Mix stock solution by adding 400-200 μL of ddH2O into the bottle of Component C, and then prepare the working solution by mixing the stock solution with assay buffer, 50X lipase stock solution and Amplite™ Red stock solution proportionally. Aliquot and store the remaining stock solutions at -80°C.

SAMPLE EXPERIMENTAL PROTOCOL

Table 2. Layout of triglyceride standards and test samples in a clear bottom 96-well microplate. STD = Triglyceride Standards (STD1-STD7, 20 to 400 µM), BL = Blank Control, TS = Test Samples.

BL	BL	TS	TS
STD 1	STD 1	...	...
STD 2	STD 2	...	...
STD 3	STD 3
STD 4	STD 4
STD 5	STD 5
STD 6	STD 6
STD 7	STD 7

Table 3. Reagent composition for each well.

Well	Volume	Reagent
STD1 - STD7	50 µL	Serial Dilutions (20 to 400 µM)
BL	50 µL	PBS
TS	50 µL	Test Sample

Prepare triglyceride standards (STD7 to STD1), blank controls (BL), and test samples (TS) according to the layout provided in Table 2. For a 384-well plate, use 25 µL of reagent per well instead of 50 µL.
Add 50 µL of Triglyceride working solution to each well of test sample, blank control, and triglyceride standards. For a 384-well plate, add 25 µL of Triglyceride working solution into each well instead.
Incubate at 30-60 minutes at RT, protected from light.
Monitor the absorbance at 575 nm.
