Objektif:

4- hydroxyethyl piperazin etil sulfonic asid se yon tanpon byolojik; Reyaksyon an nan separasyon an ak analiz nan tanpon eleman RNA, tanpon, tanpon ibridizasyon davans; Itilize pou RNA ak T4RNA ligase 3'- tèminal make; Itilize nan twous dyagnostik byochimik, twous ekstraksyon ADN/RNA ak twous dyagnostik PCR. Pou fonksyon selil ki pa enfekte. Li se yon kalite tanpon idwojèn ion, ka kontwole sijè ki abòde lan valè pH konstan a pou yon tan long. Sèvi ak konsantrasyon final la nan 10-50 tandans pou L, mwayen kilti jeneral ki gen 20 tandans LHEPES tanpon kapasite ta ka reyalize.
