15 Mata 2025
INGINGO ZOSE N'AMAKURU Y’IBICURUZWA BITANZWE KURI URU RUBUGA BISANZWE KUBONA AMAKURU N'INTEGO Z'UBUREZI.
Ibicuruzwa byatanzwe kururu rubuga bigenewe gusa mubushakashatsi bwa vitro. Mu bushakashatsi bwa vitro (Ikilatini: * mu kirahure *, bisobanura mu bikoresho by'ibirahure) bikorwa hanze y'umubiri w'umuntu. Ibicuruzwa ntabwo ari imiti, ntabwo byemejwe n’ikigo cy’Amerika gishinzwe ibiryo n’ibiyobyabwenge (FDA), kandi ntigomba gukoreshwa mu gukumira, kuvura, cyangwa gukiza indwara iyo ari yo yose y’ubuvuzi, indwara, cyangwa indwara. Birabujijwe rwose n'amategeko kwinjiza ibyo bicuruzwa mumubiri wabantu cyangwa inyamaswa muburyo ubwo aribwo bwose.
Uburyo bwo kubika Peptide
Peptide ivanze, bitewe na aside amine yihariye ikurikirana hamwe nuburyo butandukanye, bifite ibimenyetso biranga ibikorwa byabo byibinyabuzima byibasirwa cyane n’ibidukikije. Impamvu y'ibanze yo kubika peptide ni ukurinda imiti y’imiti nko kwangirika, okiside, hamwe no kwegeranya, bityo bikagumana ubusugire bwimiterere n'imikorere yibinyabuzima. Mu buryo bwa shimi, imiyoboro ya peptide irashobora kwibasirwa n’ihungabana rya hydrolytike, mu gihe amatsinda y’uruhererekane rw’uruhande ashobora kwitwara hamwe n’ubushyuhe bw’ibidukikije, ogisijeni, cyangwa mikorobe, bigatuma peptide idakora. Uburyo busanzwe bwo kubika burimo ububiko bukomeye bwa leta hamwe nububiko bwa leta. Ububiko bukomeye bwa leta busanzwe burimo guhindura peptide mu ifu yumye hakoreshejwe tekinoroji nko gukonjesha cyangwa gukama vacuum kugirango bigabanye ingaruka z’ubushuhe; ububiko-bwamazi bubika peptide mumashanyarazi akwiye, bikwiranye na ssenariyo isaba kwitegura-gukoresha peptide yashonze.
Ibitekerezo Byingenzi Kubika Peptide
Kwirinda Oxidation nikintu cyingenzi mububiko bwa peptide. Amavuta acide arimo sulfure hamwe na acide ya amine acide muri molekile ya peptide ikunda guhura na okiside hamwe na ogisijeni, bigatuma urunigi rwa peptide rucika cyangwa gushiraho imiyoboro idahwitse ya disulfide. Ingamba zihariye zirimo: kwinjiza imyuka ya inert mubikoresho byabitswe mugihe cyo kubika ibintu bikomeye kugirango yimure umwuka kandi igabanye umwuka wa ogisijeni; kongeramo antioxydants ikwiye kubisubizo byamazi ya peptide, wirinda kumara igihe kinini uhumeka ikirere, no kuzuza ibikoresho kugeza kumurongo kugirango ugabanye umwuka wa ogisijeni usigaye mumutwe.
Kwirinda Ubushuhe Kwirinda ni ngombwa mu kubungabunga peptide. Ubushuhe burashobora gutangiza hydrolytike kandi bikoroshya gukura kwa mikorobe. Kubika-leta ikomeye, ifu ya peptide yumye igomba kubikwa ahantu hafite ubushyuhe buke (≤40% ugereranije nubushuhe) ukoresheje ibikoresho birwanya ubushuhe hamwe na desiccants hanyuma bigahita bifungwa ako kanya nyuma yo kubikoresha kugirango birinde kwinjiza amazi. Mububiko bwa leta-bwamazi, ibishishwa bigomba kugira umwuma mwinshi, kandi ibikoresho bigomba kuba byumye kandi bifite isuku mugihe cyo gutegura igisubizo kugirango birinde ihungabana riterwa numwanda.
Igenzura ry'ubushyuhe ni ikindi kintu cy'ingenzi. Peptide yerekana kwihanganira ubushyuhe butandukanye; ibyinshi birashobora kubikwa kuri -20 ° C cyangwa -80 ° C muburyo bukomeye kugirango bigabanye umuvuduko wa molekile hamwe nubushakashatsi bwimiti buhoro. Amazi ya peptide yamazi arashobora kubikwa mugihe gito kuri 4 ° C (firigo) cyangwa igihe kirekire kuri -20 ° C cyangwa munsi (gukonjesha), hirindwa byimazeyo kuzunguruka inshuro nyinshi, bishobora gutera peptide cyangwa gutakaza ibikorwa. Mbere yo gukuraho ibisubizo mubice bito byemerera gukoreshwa kubisabwa kandi bigabanya inshuro nyinshi.
Guhitamo Ububiko bwa Peptide
Guhitamo ibikoresho byo kubika peptide bisaba gutekereza cyane kubintu, gukora kashe, hamwe nibisabwa. Ibikoresho bisanzwe birimo ibirahuri na plastiki. Ibikoresho by'ibirahure, hamwe nubusembure buhebuje bwa chimique, birakwiriye kuri peptide yunvikana kumikoreshereze yibintu, nubwo bigomba kwitonderwa kugirango wirinde kumeneka guterwa nubushyuhe. Ibikoresho bya plastiki bitanga ibintu byoroshye kandi birwanya ingaruka, ariko peptide zimwe na zimwe zirashobora kwiyegereza hejuru ya plastike - cyane cyane ku bushyuhe buke - byemeza ko hakoreshwa ibikoresho bya pulasitiki bitunganijwe neza cyane mu bihe nk'ibi. Ikidodo c'indege kirakomeye; Ibikoresho bya screw-cap hamwe na cryovial hamwe na reberi O-impeta zikoreshwa mugutandukanya peptide mukirere, ubushuhe, na mikorobe. Ibikoresho bya kontineri bigomba guhuza nubunini bwububiko hamwe nibikenerwa gukoreshwa: amacupa yo munwa yagutse kugirango yoroherezwe mububiko bukomeye bwa leta, hamwe na centrifuge tubes cyangwa cryovial kugirango byoroherezwe kubikwa no kubika ubushyuhe buke mubisabwa na leta.
Amabwiriza rusange yo kubika Peptide
• Kurikiza byimazeyo amahame remezo akurikira:
• Bika ifu ya peptide ikomeye mu bushyuhe buke (≤-20 ° C), yumye (ubuhehere ≤40%), hamwe n’ibidukikije bikingira urumuri.
• Kubisubizo byamazi ya peptide, koresha firigo mugihe gito cyangwa gukonjesha igihe kirekire.
• Irinde gusubiramo inshuro nyinshi.
• Kugabanya umwuka mubi mugihe ukoresha ifu ya peptide ikomeye.
Funga peptide yamazi neza hamwe nubunini buke bwumutwe.
• Koresha ibintu bitagaragara cyangwa bipfunyika aluminium ya peptide yorohereza urumuri.
