如果需要无菌溶液，则应采用无菌过滤而非高压灭菌。时间一长，亚精胺将发生脱氨基作用；溶液应采用冷冻保存。通常需要配制新溶液。

Spermidine has several applications beyond its chemical behavior as a base. The amino groups can interact with the phosphate groups of DNA and RNA and stabilize them. In addition, spermidine has a positive impact on transcription by RNA polymerases and can be found in several buffers. Within RNA bioprocessing, spermidine can be used for purification to bind and precipitate DNA. It may also be considered as adjuvant for mRNA vaccines.

The EMPROVE^® Expert quality grade provided with this product is tested for microbial and endotoxin levels and is RNase- and DNase-free. Stability studies according to ICH Q7 are running and stability conclusions will be available via EMPROVE^® Suite.
