Ultramicrospectrophotometer

Kev Taw Qhia Txog Khoom

Ultramicrospectrophotometer yog ib hom kev ntes ceev thiab raug ntawm nucleic acid, protein thiab cell solution concentration yam tsis tau preheating, qhov loj ntawm cov qauv tsuas yog 0.5 txog 2ul, thiab hom cuvette tuaj yeem ntes tau qhov concentration ntawm cov kab mob thiab lwm yam kab lis kev cai. Fluorescence detection function tuaj yeem ua ke nrog fluorescence quantitative analysis kit, los ntawm kev sib xyaw ua ke ntawm fluorescent dyes thiab cov tshuaj uas lub hom phiaj tuaj yeem ntsuas DNA, RNA thiab protein concentration, thiab qhov tsawg kawg nkaus tuaj yeem ncav cuag 0.5pg / μl (dsDNA).

Cov yam ntxwv ntawm cov khoom

Lub teeb ci ntsa iab zaus luv luv, piv rau txoj kev nrhiav pom ib txwm muaj los ua kom lub neej ua haujlwm ntawm lub teeb ci ntev dua. Kev txhawb nqa lub teeb ntawm cov khoom sim me me tuaj yeem nrhiav tau sai dua, tsis yooj yim rau kev puas tsuaj.;

Kev ua haujlwm fluorescence: Nrog fluorescence quantitative reagent tuaj yeem ntes pg concentration dsDNA;

4 txoj kev nrhiav pom kev siv tshuab: kev tswj hwm lub cev muaj zog tshwj xeeb, kev siv "4" hom kev nrhiav pom kev siv tshuab, kev ruaj khov, rov ua dua, linearity zoo dua, qhov ntsuas ntau dua;

Lub tshuab luam ntawv uas ua rau hauv: Nrog rau cov kev xaiv yooj yim siv rau cov ntaub ntawv luam ntawv, koj tuaj yeem luam tawm cov ntawv qhia ncaj qha los ntawm lub tshuab luam ntawv uas ua rau hauvr;

OD600 cov tshuaj tua kab mob, kev tshawb pom kab mob me me: nrog OD600 optical path detection system, dua li hom tais diav yooj yim rau cov kab mob, cov kab mob me me thiab lwm yam kab lis kev cai tshuaj nrhiav kom pom tseeb;

Kev rov ua dua siab thiab linearity;
