Ucoceko oluPhezulu lwePDRN iMigangatho yoBubunzima beMolekyuli yaBavelisi bezoNyango kunye nezoCosmetic 

Intshayelelo 
I-Polydeoxyribonucleotide (PDRN) yipolymer esebenzayo yamaqhekeza amafutshane e-DNA asanda kusetyenziswa njengemathiriyeli ekrwada esebenzayo kunyango lokulungiswa kwamanxeba, iinaliti kunye neefomyula zeprayimari zokunakekelwa kwesikhumba. Kubavelisi kunye namaqela okuthenga, eyona nto ibalulekileyo ye-PDRN ibaluleke kakhulu ukuhanjiswa kobunzima bemolekyuli - ubungakanani obuchanekileyo kunye nobungakanani beeqhekeza zeDNA kuninzi oluchaphazela ngokuthe ngqo ukusebenzisana kwezicubu, ukuzinza kwemveliso kunye nokulungelelaniswa kokulawula. Eli nqaku libonisa isikhokelo esijolise kumthengisi kwiibhendi zobunzima bemolekyuli ezamkelweyo kwizicelo ezahlukeneyo, iindlela zelabhoratri ezisebenzayo zokuqinisekisa, ulawulo lomgangatho oyimfuneko, kunye nemibuzo echanekileyo yokuthengwa kwempahla kunye namaqela e-R&D kufuneka abuze ngaphambi kokubeka iodolo yesambuku.

Yintoni i-PDRN kunye nendlela ubungakanani beqhekeza obuchaphazela ngayo ukusebenza

I-PDRN lulungiselelo olusulungekileyo lwamaqhekeza amafutshane, anomgca we-deoxyribonucleotide. Kunokuba imolekyuli enye, iPDRN yi umxube umsebenzi wayo webhayoloji uvela kubuninzi obunxulumene nobungakanani bamacandelo ahlukeneyo. Ubude beqhekeza bumisela indlela imolekyuli esasazeka ngayo kwiithishu, ukuba ihlala ixesha elingakanani, kwaye zeziphi iindlela zeselula ezisebenzisayo-ke, ayizizo zonke iipowder zePDN ezinokutshintsheka. Umniki-nkonzo olawula ukuhanjiswa kweqhekeza kunye namaxwebhu anciphisa ngokucacileyo umngcipheko woqulunqo kubavelisi.

Izindululo zobunzima beemolekyuli ezicetyiswayo ngokwesicelo

Uluhlu olungezantsi luneenkcukacha ezisebenzayo abavelisi abadla ngokuzicela. Zisebenzise njengendawo yokuqala xa uthethathethwano ngeempawu zemveliso okanye ucela iisampulu eziqinisekisiweyo.

Qaphela: ezi band iindawo ekujoliswe kuzo. Abathengi kufuneka bacele elona jiko losasazo (umzekelo, i-histogram okanye ichromatogram) kunexabiso "eliphakathi" elinye.

Abavelisi baqinisekisa njani ukuhanjiswa kobunzima bemolekyuli

Abathengisi abathembekileyo banikezela ngedatha yovavanyo lwe-orthogonal. Iindlela eziqhelekileyo kunye nezamkelweyo ziquka:

• Ubungakanani bokungabandakanywa chromatography (SEC / GPC) - indlela ephambili yokufumana i-molecular-weight distribution curve kunye nokubala i-Mn / Mw kunye ne-polydispersity (PDI).

• I-HPLC enokubonwa kwe-UV - isetyenziselwa ukuqinisekisa ukucoceka kweekhemikhali kunye nokulinganisa umxholo we-nucleic acid.

• Imasa spectrometry (umzekelo, MALDI-TOF) - iluncedo ekusombululeni iipatheni eziphakamileyo ze-oligomers ezincinci kunye nokuqinisekisa ubuninzi bobunzima.

• I-UV spectrophotometry (umlinganiselo we-A260/A280) - khangela ngokukhawuleza ukucoceka kwe-nucleic acid kunye nokungcoliswa kweeprotheyini.

• I-Endotoxin (LAL) kunye novavanyo lwe-sterility - kubalulekile kumabakala atofwayo.

Yintoni onokuyicela kubathengisi: iichromatograms eluhlaza (i-GPC traces), ixabiso le-Mw kunye ne-Mn, i-PDI, iindlela zokuvavanya kunye nemodeli yezixhobo, kunye ne-batch epheleleyo ye-COA.

Ulawulo olubalulekileyo lomgangatho kunye neeparamitha zolawulo lwe-PDRN yodidi lwezonyango

Xa imveliso yakho izakusetyenziswa ekwenzeni iimveliso zonyango okanye ezitofwayo, gxininisa kolu lawulo lubhaliweyo:

• I-COA enokuhanjiswa kwe-MW (iqhotyoshelwe ichromatogram yeGPC)

• Ipesenti yococeko lweDNA (iziphumo zeHPLC)

• Umda we-Endotoxin (EU / mg) kunye nengxelo yovavanyo lwe-LAL

• Iziphumo zovavanyo lokuzala (yeefomati ezinyumba)

• Iintsimbi ezinzima (Ingxelo ye-ICP-MS ye-Pb, Hg, As, Cd)

• Imida yeMicrobial (umthwalo wendalo)

• Idatha yokuzinza (ikhawulezayo kunye nexesha lokwenyani)

• Imigangatho yemveliso (isatifikethi se-cGMP, ubungqina bophicotho-zincwadi)

• Ukulandeleka (imvelaphi yempahla ekrwada, amanani eqashiso kunye nekhonkco lokugcinwa)

Ababoneleli ababandakanya iindlela ze-SOPs kunye neerekhodi zolungelelwaniso lwezixhobo zibonisa ukulungela uphicotho oluphezulu.

Uluhlu lokukhangela intengo — imibuzo enokubuzwa kumboneleli ngamnye wePDRN

1. Yintoni na ngqo ukuhanjiswa kobunzima bemolekyuli yebhetshi (nikeza ichromatogram yeGPC)?

2. Yiyiphi iindlela zohlalutyo kunye nezixhobo zisetyenziselwe ukulinganisa iMW kunye nobunyulu?

3. Ngaba unokubonelela I-COA, ingxelo ye-endotoxin, isinyithi esinzima, kunye nedatha yokuzinza ngeqashiso?
