Product overview
Deproteinizing Sample Preparation Kit - TCA (ab204708) offers a simple method to prepare samples for use in assays to measure small molecules, such as lipids, metabolites, metal ions etc.
This kit is useful where endogenous enzymes and other proteins would interfere with the assay, or would act directly to affect the level of the analyte to be measured, or would bind the analyte.
In this kit, trichloroacetic acid (TCA) is used to precipitate proteins by drastically lowering the sample pH. After removal of precipitated proteins, the pH of the sample is neutralized with neutralization buffer that is provided in the kit. Small molecules present in the sample can then be easily analyzed without interference from endogenous enzymes and other proteins .
The kit is easy to follow, convenient, and can be utilized for the preparation of a large number of samples in parallel. Samples prepared using this kit can be directly used in various bioassays.

Effect of TCA amount on deproteinization:
Aliquots of pooledhuman serum (off the clot, 100 μL) were treated with different amounts of TCA following the kit protocol. Estimated protein concentration before deproteinization: 7.9 g/dL. More than 99% of protein was removed using less than 10 μL of TCA/100 μL human serum. Red solid line = Total protein; blue dotted line = sample treated with TCA; green solid line = sample treated with spin column.

ab 204708Comparison of analysis of lactate:
Human serum samples (100 μL) were analyzed for lactate concentration using L-Lactate Assay Kit (Colorimetric) (ab65331). Untreated samples (purple line) show higher signal when compared to TCA treated samples (red line). However, background signal is very similar in both untreated (green line) and treated (blue line) samples.
