I-Lyophilized Peptide
I-Lyophilized Peptide yi-peptide compound eyenziwe zii-amino acid ezininzi ezidityaniswe zii-peptide bonds. Ubunzima bayo beemolekyuli buqhele ukuba phakathi kwamakhulu ambalwa ukuya kumawaka ambalwa eeDalton kwaye inomsebenzi onamandla webhayoloji. Ngokwesiqhelo i-white okanye phantse emhlophe i-amorphous powder, ene-hygroscopicity kunye nokunyibilika kakuhle kwamanzi. Inyibilika emanzini, inyibilikise i-asidi, kwaye inyibilikise izisombululo ze-alkali, kwaye ayinyibiliki kwi-organic solvents. Iintlobo ezahlukeneyo ze-Froze-dryed powder zinokwenziwa ngee-amino acids ezahlukeneyo, kwaye ubunzima bazo beemolekyuli bunokwahluka. Ulwakhiwo lweekhemikhali lwee-peptides ezomisiweyo ngokuqandisa lumisela imisebenzi yazo eyahlukeneyo yebhayoloji kunye nemiphumo ye-pharmacological, efana ne-antioxidant, i-anti-inflammatory, kunye nolawulo lomzimba. Le misebenzi inxulumene kakhulu nolandelelwano lwe-amino acid, ukwakheka kweemolekyuli, kunye nokusebenzisana phakathi kweemolekyuli kwiimolekyuli ze-peptide ezomisiweyo ngokuqandisa. Ibuthathaka kwizinto ezingqongileyo ezifana nokukhanya, ubushushu, kunye ne-oxygen, kodwa inozinzo oluthile phantsi kweemeko ezithile. Umzekelo, phantsi kweemeko ze-acid okanye ze-alkaline, ii-peptides ezomisiweyo ngokuqandisa zinokugcina isakhiwo sazo kunye nomsebenzi webhayoloji. Ukupakisha kweemveliso ze-lyophilized yi-lyophilized powder kwi-vial.

Indlela yokulungiselela i-lyophilized peptide ibandakanya ikakhulu la manyathelo alandelayo:
Khetha ii-amino acids ezikumgangatho ophezulu, iipeptides, kunye nezinye izinto ezikrwada, kwaye wenze unyango oluyimfuneko olufana nokususa umbala kunye nokubulala iintsholongwane. Ezi zinto zingafunyanwa ngeendlela ezinje ngokwenziwa kweekhemikhali, ukubiliswa kwezinto eziphilayo, kunye netekhnoloji yobunjineli bemfuza.
Lungisa ii-amino acids okanye iipeptides zibe sisisombululo soxinzelelo oluthile kwinkqubo yokulungiselela elandelayo. Izisombululo ze-dilute acid okanye ze-alkali zingasetyenziswa njengezinyibilikisi, kunye nezinyibilikisi ze-organic ezifana ne-anhydrous ethanol kunye ne-methanol. Ngexesha lenkqubo yokulungiselela, kufuneka kuqwalaselwe iiparameter ezilawulayo ezifana nexabiso le-pH, ubushushu, kunye noxinzelelo.
Phantsi kweemeko zobushushu obuphantsi, amanzi kwisisombululo asuswa ngeteknoloji yoxinzelelo lwe-vacuum ukuze kufunyanwe isisombululo esixineneyo. Uxinzelelo lwe-vacuum lunokunciphisa ubushushu, luthintele ukuguquka okanye ukusabela kwe-oxidation okubangelwa bubushushu obuphezulu, kwaye lugcine umsebenzi webhayoloji weepeptides. Uxinzelelo kunye nenqanaba lokomisa kwesisombululo esixineneyo kunokuchaphazela ubukhali kunye nokuzinza kweepeptides ezomileyo eziqandisiweyo.
Isisombululo esixineneyo siphathwa ngokuqandisa ukuze kususwe umswakama oseleyo kwaye kufumaneke iipeptide ezomisiweyo. Ukomisa ngokuqandisa kungenziwa kumaqondo obushushu aphantsi ukuthintela ukuguquka kwendalo okanye ukusabela kwe-oxidation okubangelwa ngamaqondo obushushu aphezulu. Ngexesha lenkqubo yokomisa ngokuqandisa, kuyimfuneko ukulawula iiparameter ezifana nobushushu, uxinzelelo, kunye nexesha lokomisa ukuqinisekisa ukuveliswa kweepeptides zokomisa ngokuqandisa ezikumgangatho ophezulu.
Iipeptides ezomisiweyo ezifunyenweyo zipakishwe ukuze zikhusele umgangatho kunye nomsebenzi wazo. Izinto zokupakisha kufuneka zikhethwe ezivalwe kakuhle, ezingangeni kumswakama, nezingenakukhanya, ezifana neebhotile zeglasi, iibhotile zeseramikhi, iitini zesinyithi, njl. Ngaphambi kokupakisha, kufuneka kwenziwe uvavanyo lomgangatho, olufana nembonakalo, ukunyibilika, uzinzo, njl. njl., ukuqinisekisa ukuba umgangatho wemveliso uyahlangabezana nemigangatho.
Ulawulo olungqongqo lomgangatho kufuneka lwenziwe ngexesha lenkqubo yokulungiselela ukuqinisekisa ukuba inyathelo ngalinye lokusebenza lihambelana nemigangatho kunye nemigangatho. Umzekelo, uvavanyo lomgangatho wezinto eziluhlaza, ulawulo loxinzelelo lwesisombululo kunye nexabiso le-pH, ukujonga uxinano lobushushu obuphantsi kunye neenkqubo zokuqandisa ngokukhenkceza, njl. Okokugqibela, uvavanyo lomgangatho kufuneka lwenziwe kwimveliso, njengohlalutyo lwe-infrared spectroscopy, uhlalutyo lwe-chromatography yolwelo olusebenza kakuhle, njl. njl., ukuqinisekisa ubunyulu kunye nomgangatho wemveliso.
Iipeptides ezomileyo eziqandisiweyo ngokubanzi kufuneka zigcinwe kumaqondo obushushu aphantsi ukuze kugcinwe ulwakhiwo lwazo kunye nomsebenzi wazo webhayoloji. Ke ngoko, imveliso kufuneka igcinwe kwindawo epholileyo neyomileyo, kuthintelwe ukukhanya kwelanga ngqo kunye namaqondo obushushu aphezulu. Ngexesha lokuthuthwa, kufuneka kuqwalaselwe nemilinganiselo efana nokumelana nokutsha, ukungangeni manzi, kunye nokumelana nokufuma ukuqinisekisa ukhuseleko kunye nokuzinza kwemveliso.
Ngamafutshane, indlela yokulungiselela i-lyophilized peptide ifuna ulawulo oluqinileyo lomgangatho wezinto eziluhlaza, iimeko zokusebenza, kunye nolawulo lomgangatho ukuqinisekisa iimveliso ze-peptide ezomisiweyo ezisemgangathweni ophezulu. Kwangaxeshanye, kufuneka kuqwalaselwe uzinzo kunye nokhuseleko lwemveliso ngexesha lokugcina nokuthuthwa.
