4. Dawb radical referctions: nws tuaj yeem siv dawb radical kho cov tshuaj tiv thaiv uas cov iodine radicals yog tsim uas tuaj yeem koom nrog kev hloov tshuaj ntxiv.
5. Peptide synthesis: NIS qee zaum siv nyob rau hauv peptide Coupling kev tawm los qhia iodine rau hauv cov kab txuas peptide.
Khw ntawm 2-8 ° C nyob rau hauv qhov chaw txias, qhuav thiab zoo-ventilated tsev rau khoom.
Tseg deb ntawm hluav taws thiab cov khoom cua sov. Zam kev tshav ntuj ncaj qha.
Lub pob yog ntim. Nws yuav tsum tau muab cais cais tawm los ntawm cov kua qaub thiab cov tshuaj noj, thiab kev sib xyaw sib xyaw yuav tsum tsis txhob zam.
Thaj chaw cia yuav tsum tau nruab nrog cov ntaub ntawv tsim nyog los muaj cov to.
1. Thawv: Khw nis hauv lub khob thawj lossis hauv lub khob kaw kom nruj ib ce lossis lub raj mis yas los tiv thaiv kom tsis txhob muaj kev nqus thiab paug.
2. Kub: Khw nis hauv qhov chaw txias, qhuav, nyiam dua ntawm chav tsev kub lossis hauv lub tub yees. Zam kev kub ntxhov lossis kev tshav ncaj qha.
3. Cov av noo: vim tias nis yog rhiab rau ya raws, nws yog ib qho tseem ceeb kom khaws nws hauv qhov chaw noo nyob hauv ib puag ncig. Yog tias tsim nyog, txiav txim siab siv tus desiccant nyob rau hauv lub thawv ntim khoom.
4. Kev ceev faj kev nyab xeeb: khw muag khoom kom deb ntawm cov khoom tsis sib xws (xws li muaj zog txo cov neeg sawv cev) thiab xyuas kom nws tau txais kev ncav cuag ntawm cov menyuam yaus thiab tsiaj.
5. Daim ntawv lo: daim ntawv lo qhia kom meej nrog lub npe tshuaj lom neeg, kev xav, thiab qee cov ntaub ntawv cuam tshuam kev phom sij.

1 kg / hnab los yog 25 kg / nruas lossis 50 kg / nruas lossis raws li cov neeg siv khoom yuav tsum tau ua.
1. Kev tswj hwm ua raws: Tshawb xyuas thiab ua raws li cov kev tswj hwm hauv zos, thiab thoob ntiaj teb hais txog kev thauj mus los ntawm cov khoom phom sij. NIS yuav raug cais raws li cov khoom tsim kev phom sij, yog li paub tseeb tias txhua yam ntaub ntawv thauj khoom muaj tseeb thiab ua tiav.
2. Ntim: Siv cov ntaub ntawv ntim uas tsim nyog uas tsim nyog nrog nis. Feem ntau, qhov no suav nrog kev siv cov ntim khoom muaj zog, xau cov khoom ntim uas tuaj yeem tiv thaiv lub cev kev ntxhov siab ntawm kev xa khoom. Xyuas kom meej tias lub npe tshuaj lom neeg thiab cov cim kev phom sij yog cim rau hauv lub khob.
3. Sau npe: sau npe kaw kom meej nrog cov lus ceeb toom kev phom sij, xws li cov ntaub ntawv kev nyab xeeb (piv txwv li, "oxidization" yog tias nqos "). Suav cov lus qhia thiab cov ntaub ntawv tiv toj thaum muaj xwm txheej ceev.
4. Kev tswj qhov kub: Yog tias tsim nyog, xyuas kom cov kev thauj cov qauv uas muaj cov kev mob uas tsim nyog los tiv thaiv kev ua kom muaj kev cuam tshuam rau qhov ntsuas kub.
5. Zam kev yaa dej: Txij li nes yog rhiab rau ya raws, thov xyuas kom meej tias ntim yog cov pov thawj noo noo. Txiav txim siab siv tus desiccant kom nqus cov dej noo thaum xa khoom.
6. Kev Thauj Mus Los: Xaiv txoj hauv kev thauj mus los uas txo qis kev pheej hmoo ntawm kev puas tsuaj lossis kis tau. Txiav txim siab siv lub tuam txhab shipping uas tshwj xeeb hauv kev tuav cov khoom txaus ntshai.
7. Cov txheej txheem thaum muaj xwm ceev: Xws li cov ntaub ntawv ntawm cov txheej txheem thaum muaj xwm txheej ceev thaum muaj dej xau lossis huam yuaj thaum caij tsheb thauj mus los. Qhov no yuav tsum muaj cov ntaub ntawv tiv toj ntawm pab pawg xwm txheej ceev.
8. Kev kawm: Ua kom cov neeg ua haujlwm tau koom nrog kev thauj khoom thiab kev thauj mus los ntawm NIS tau kawm ua kev phom sij thiab nkag siab txog kev pheej hmoo.
Yog, n-iodosuccinimide (NCE) yog kev phom sij rau tib neeg. Ntawm no yog qee cov ntsiab lus tseem ceeb txog nws lub peev xwm ua mob:
1. Toxicity: NIS yog lom neeg yog noj, nqus tau, lossis nqus tau ntawm daim tawv nqaij. Nws yog khaus rau daim tawv nqaij, ob lub qhov muag, thiab ua pa rau kev ua pa.
2. Iritation: Tiv tauj nrog NIS yuav ua rau tawv nqaij thiab qhov muag khaus. Zam kev sib cuag ncaj qha thiab siv cov khoom tiv thaiv tus kheej tsim nyog (PPE) thaum tuav.
3. Cov tib neeg muaj txiaj ntsig: Qee tus neeg yuav ua tsis tau kev ua tsis haum lossis rhiab tom qab raug rau nIS.
4. Handling ceev faj: Thaum siv NIS, ib txwm siv hauv cov hnab looj tes zoo, qhwv ntsej muag, thiab ua raws li cov lus qhia kev nyab xeeb thiab ua kom muaj kev nyab xeeb.
5. Thawj qhov kev pab cuam: yog kev sib cuag nrog tshuaj yeeb, xws li yaug txoj kev cuam tshuam nrog dej thiab nrhiav kev kho mob yog tias tsim nyog.
