A typical CYP reaction length is 1-2 h, but CYP activity can survive longer at 37 °C. Figure 9.3 shows that product turnover of the CYP reactions occurred over a 6 h incubation (Li, unpublished results). UGT activity can last longer than 24 h [23], With accumulation of product, secondary reactions, such as further oxidation of product or hydrolysis of glucuronide, may become noticeable. Therefore, monitoring the reaction with HPLC-U V-MS is critical for identifying the best time to terminate the reaction. 

Tannic acid can be added to the prefixative (1—4% w/v) in cacodylate buffer, or tannic acid in 0.1 M buffer 1-2 h can be used after osmication between fixation and dehydration. 

Tannic acid Tannic acid can be added at 1-4% w/v in either cacodylate-buffered glutaraldehyde or glutaraldehyde-formaldehyde or between prefixation and postfixation (immerse specimens 1-2 h in tannic acid in 0.1M buffer) Tonoplast...
