PURIFIED PROSTATIC TISSUE ANTIGEN |
摘要 |
<p>33 PURIFIED PROSTATIC TISSUE ANTIGEN A prostate antigen distinct from prostatic acid phosphatase has been detected in normal, benign hypertrophic and mallgnant prostatic tissues, but not in other human tissues. The prostate antigen was purified to homogeneity from prostatic tissues by ammonium sulfate precipitation, DEAE-BioGel A anion exchdnge chromatography, molecular sievings on Sephadex G-1OO and Sephadex G-75, and preparative polyacrylamide gel electrophoresis. The purified prostate antigen shows a single protein band on analytical polyacrylamide gel electrophoresis and ispelectric focusing. The molecular weight of purified antigen was estimated by Sephadex G-75 gel filtration to be 33,000 and by sodium dodecyl sulfate polyacrylamide gel electrosphoresis to be 34,000 with no subunit. The prostate antigen had an isoelectic point of 6.9. Attornery's Ducket No. 90726 Client's Project No. 280-1218</p> |
