Palmitoyl Tetrapeptide-20 /GT Peptide/Peptide Supplier

Tsanangudzo

Palmitoyl tetrapeptide 20 (PTP20) inonzi biomimetic peptide inotorwa kubva ku-α-melanocyte-stimulating hormone (α-MSH).Iyi inoteedzana yakasarudzwa kuti iwirirane neyayo receptor MC1-R.Muchidimbu, peptide iresin yakagadzirwa paDEG-amino methyl boka (DEG-AM) neiyo solid-phase musangano uchishandisa diisopropyl carbodiimide/ethyl 2-cyano-2 -(hydroxyimino) acetate (DIC/Oxyma) semubatanidzwa unotevera. chirongwa chefluorenyl-methoxycarbonyl, ine Ramage linker.Kucheka O / dithiothreitol (DTT) kubva mumucheka wakaitwa uchishandisa trifluoroacetic acid (TFA) / H 2. Zvadaro, peptide yakanga yakasvibiswa uye yakabviswa kubva mumucheka."Mushure meizvozvo, ion exchange inowanikwa kushandura trifluoroacetate kuita acetate."Iyo inewo mhedzisiro yekuchenesa.Peptide kuchena kwakaongororwa neyakadzoserwa-chikamu chepamusoro-kudzvanywa kwemvura chromatography uchishandisa A symmetric column (250 × 4.6 mm), kushandisa mutsara gradient (A: 0.1% TFA/ mvura / B: 0.1% TFA/ acetonitrile; B kubva pa40 kusvika ku100 % pamusoro pemaminitsi makumi matatu).Kuchena kwayo kwakapfuura 90% uye yakawedzera kuratidzwa nehukuru spectrometry.

FAQ:

Ndeipi magumo akanakira tsvakurudzo yangu?

Nekusagadzikana, iyo peptide inopera neN-terminal yemahara amino boka uye C-terminal yemahara carboxyl boka.Kutevedzana kwepeptide kazhinji kunomiririra kutevedzana kweprotein yaamai.Kuti uve pedyo neprotein yaamai, kupera kwepeptide kunowanzoda kuvharwa, kureva, n-terminal acetylation uye C-terminal amidation.Ichi chigadziriso chinodzivirira kuunzwa kwechaji yakawandisa, uye zvakare inoita kuti ikwanise kudzivirira exonucliase chiito, kuitira kuti peptide iwedzere kugadzikana.

Ndeipi yakagadziridzwa yakanyorwa polypeptides inogona kugadzirwa muChinese peptide?

Kambani yedu inopa akasiyana siyana akagadziridzwa peptide labeling, senge acetylation, biotin labeling, phosphorylation gadziriso, fluorescence gadziriso, inogona zvakare kugadzirwa zvinoenderana nezvako zvakakosha zvaunoda.

Iwe unopedza sei polypeptides?

Iko kunyungudika kwepolypeptide kunoenderana zvakanyanya neiyo yekutanga uye yechipiri chimiro, chimiro chekuchinja label, solvent mhando uye yekupedzisira kusungirirwa.Kana iyo peptide isinganyungudika mumvura, Ultrasound inogona kubatsira kuinyungudutsa.Kune peptide yakakosha, inokurudzirwa kunyungudika ne10% acetic acid;Kune acidic peptides, kuparara ne10% NH4HCO3 kunokurudzirwa.Organic solvents inogonawo kuwedzerwa kune insoluble polypeptides.Iyo peptide inonyungudika mune ishoma huwandu hwe organic solvent (semuenzaniso, DMSO, DMF, isopropyl doro, methanol, nezvimwewo).Zvinokurudzirwa zvikuru kuti peptide inyungudiswe muorganic solvent kutanga yozowedzera zvishoma nezvishoma kumvura kana imwe buffer kusvika yadiwa.

Ndeapi mamiriro ekuchengetedza akanakisa?Iyo peptide yakagadzikana sei?

Mushure mokunge lyophilized, polypeptide inogona kuumba fluff kana flocculant poda, iyo inogona kudzivirira kuparara kusati kwasvika kwepolypeptide.Zvinokurudzirwa kuchengetedza mamiriro: a.-20℃nzvimbo yekuchengetera kana yakaoma b.Edza kunzvenga chando chisingaperi c.Edza kudzivirira kuchengetedza mumhinduro (yakaoma-yakaomeswa poda inogona kuchengetwa mumapakeji akasiyana kuti zvive nyore kushandisa) d.Kana ichifanira kuchengetwa mumhinduro, zvinokurudzirwa kunyungudutsa mapeptides mumvura isina utachiona pasi pemamiriro asina simba ane acid uye chengeta pa -20.℃.

Peptide yangu inotakurwa sei?Ndeipi mishumo yebvunzo inopiwa?

Ese mapolypeptides akaomeswa nechando anowanzo kuchengetwa mumidziyo yakakosha ye2 ml kana 10ml ine data rekutanga rekuongorora uye synthesis mishumo ine ruzivo rwakakosha senge kutevedzana, huremu hwemamorekuru, kuchena, huremu, uye huwandu hwepolypeptide.

Chii chinonzi uremu net?Chii chinonzi peptide content?

Mushure mekunge lyophilized peptide inowanzoita fluffy uye fluff-senge, inogona kunge iine huwandu hwemvura, adsorbed solvents uye munyu nekuda kwehunhu hwepeptide pachayo.Izvi hazvirevi kuti kuchena kwepeptide hakuna kukwana, asi kuti iyo chaiyo yepeptide inoderedzwa ne10% kusvika 30%.Huremu hwemambure epeptide ndihwo huremu chaihwo hwepeptide kubvisa mvura nemaion ane protonated.Kuti uve nechokwadi chekusangana kwepeptide, izvo zvisiri-peptide zvinhu zvinoda kubviswa kubva kune crude peptide.

Iyo peptide inogona kuve yakachena sei?

Kambani yedu inogona kupa akasiyana mazinga ekuchena kune vatengi kusarudza kubva, kubva kune isina kuchena kusvika> 99.9% kuchena.Zvinoenderana nezvinodiwa nevatengi tinogona kupa kuchena> 99.9% Ultra-pure polypeptide.
