FAQ:

Menene shawarwarin idan na fara amfani da peptides?

Lokacin da aka shirya don amfani, bi matakan da ke ƙasa don narkar da peptides don kula da ingancin su.

1, kafin bude kwalban da auna wani ɓangare na peptide, zafi shi don isa dakin da zafin jiki, kuma ana bada shawarar lokacin dumama ya zama 1 hour.

2. Da sauri auna adadin da ake buƙata a cikin yanayi mai tsabta na waje.

3. Ajiye sauran peptides a cikin injin daskarewa ƙasa -20℃, ƙara kayan bushewa da adana su a cikin akwati marar iska.

Ina zaune a ƙasashen waje, kuma zai ɗauki kwanaki da yawa kafin a kai da kuma ba da izinin kwastam.Shin hakan zai shafi bincikena?

Kuna karɓar peptides a cikin fakitin foda na lyophilized, kuma ana iya adana peptides a yawan zafin jiki ba tare da lalacewa ba.Da fatan za a daskare kuma adana nan da nan bayan an karɓa.

Wadanne matsaloli ya kamata a kula da su a cikin tsarin ajiya?

An shirya peptide da kuka karɓa a cikin foda mai lyophilized.Peptides sune hydrophilic, kuma shayar da ruwa zai rage kwanciyar hankali na peptide kuma ya rage abun ciki na peptide.Da fatan za a kula da waɗannan abubuwa masu zuwa: na farko, tare da desiccants, adana a cikin bushe wuri.Na biyu, da zarar an karɓa, don Allah a saka a cikin injin daskarewa -20℃ajiya, domin kiyaye iyakar kwanciyar hankali.Na uku, guje wa amfani da aikin sanyi na atomatik na injin daskarewa.Canje-canje a cikin zafi da zafin jiki na iya shafar kwanciyar hankali na peptides.Na hudu, zafin jiki na waje yayin sufuri ba ya shafar inganci da ingancin peptides.

Ta yaya zan adana peptides daskararre lokacin da na karɓi samfurin?

Da zarar ka karba, dole ne ka adana shi nan da nan a -20° C ko ƙasa.

Idan abun ciki na peptide shine 80%, menene sauran 20%?
