Objective:
To detect content of bacterial endotoxin in Yuxingcao and Qingkailing injections by specific and nonspecific tachypleus amebocyte lysate technique for in order to investigate the feasibility of specific tachypleus amebocyte lysate technique for detecting bacterial endotoxin in traditional Chinese drug injections.
Method:
Different batches of Yuxingcao and Qingkailing injections were detected by specific and nonspecific tachypleus amebocyte lysate kits.
Result:
Yuxingcao injection could be detected by specific and nonspecific tachypleus amebocyte lysate technique, Whereas Qingkailing injection could be detected only by specific tachypleus amebocyte lysate.
Conclusion:
Using specific tachypleus amebocyte lysate as a substitute for nonspecific tachypleus amebocyte lysate is an effective method for detecting content of bacterial endotoxin in Qingkailing injection.

Two-dimensional Gel Electrophoresis
The first dimension separation uses the isoelectric focusing or IEF technique performed on immobilized pH gradient (IPG) strips that separate proteins according to their isoelectric points.

Effects of EDTA on End-Point Detection Methods
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a result, EDTA...
SDS-PAGE
A variation of gel electrophoresis, termed polyacrylamide gel electrophoresis (PAGE), is commonly used for separating proteins according to their molecular size by passing them through a polyacrylamide gel. Because of the varying charges associated with amino acid side chains, PAGE can be used to separate intact proteins...
