Type of article: Article

Summary

STORAGE OF TUBERS AT 283 K (10 DEG C) FOR UP TO 70 DAYS OR STORAGE OF EXTRACTS AT 213 K (-60 DEG C) FOR 70 DAYS DID NOT AFFECT ISOZYME BANDING PATTERNS. STORAGE OF FRESH EXTRACTS FOR 14 DAYS AT 278 K (5 DEG C) PRODUCED BLURRING OF ALKALINE PHOSPHATASE BANDS, ALTERED ISOZYME MOBILITY OF MALIC ENZYME, AND ADDED A BAND TO GLUCOSEPHOSPHATEISOMERASE ZYMOGRAMS. IT DID NOT AFFECT THE MOBILITY OR RESOLUTION OF 6-PHOSPHOGLUCONATE DEHYDROGENASE. ADDITION OF 0.1 M MERCAPTOETHANOL DID NOT RESTORE ORIGINAL RESOLUTIONS OR MOBILITIES.
