The determination of hydroxyproline.
There has been a great need for a satisfactory method for the determination of hydroxyproline to facilitate the study of the composition of proteins. Lang (1) and Waldschmidt-Leitz and Akabori (2) developed a calorimetric estimation involving oxidation to pyrrole with sodium hypochlorite and color formation with isatin or p-dimethylaminobenzaldehyde. However, oxidation was said to be incomplete...
متن کاملDetermination of hydroxyproline in liver.
THE DETERMINATION of hydroxyproline in parenchymous tissues such as liver presents special problems not encountered in collagenons tissues. This is true because liver contains only small quantities of this imino acid (1), and furthermore, the existing quantitative tests are nonspecific. Thus, if one were to use the usually acceptable Neuman and Logan procedure (2), a separate determination for ...
متن کاملdetermination of maximal singularity free zones in the workspace of parallel manipulator
due to the limiting workspace of parallel manipulator and regarding to finding the trajectory planning of singularity free at workspace is difficult, so finding a best solution that can develop a technique to determine the singularity-free zones in the workspace of parallel manipulators is highly important. in this thesis a simple and new technique are presented to determine the maximal singula...
15 صفحه اولModified assay for determination of hydroxyproline in a tissue hydrolyzate.
A modified assay for the determination of hydroxyproline in tissue is presented. The modifications greatly reduce the time required for analysis of excised tissue as first introduced by Stegemann and Stalder [1]. These modifications include a change in the technique for tissue hydrolysis and a change in the preparation of the hydroxyproline oxidizing agent. The analysis utilizes the standard ad...
متن کاملHydroxyproline determination in serum and gingival crevicular fluid.
A high-performance hquid chromatographic assay for total hydroxyproline in serum and gingival crevicular fiuid has been developed. The Clq component of the first complement factor was precipitated out of the samples with a 0.02 M sodium acetate solution. Ahquots of the supernatants were dried, vapor hydrolyzed with 6 M hydrochloric acid at 105°C for 24 hours and derivatized with phenylisothiocy...
