As Bruce points out, it takes less time to find the method than it did for you to post the question here. Are you always reliant on others to think for you? That is NOT a trait of a good researcher.
Bruce Neagle Mark Krause Thank you dear Bruce and Mark. Unfortunately, you misunderstood me. I needed great comprehensive details for LPA measurement protocol(colorimetric method). I saw and analyzed many paper about methods which there are for LPA assay in addition to that paper which Bruce mentioned. Of course I saw and interpreted that paper before. but I asked give exact and comprehensive detail of LPA assay in colorimetric method because I had some problem in this and other papers.
