Cell line Informatrion:
Designations: BALB/3T3 clone A31Depositors: S AaronsonGrowth Properties: adherentOrganism: Mus musculusMorphology: fibroblastSource: embryoStrain: BALB/cCell Type: fibroblastIsolation date: 1968Applications: transfection hostVirus Susceptibility: Human poliovirus 1, Herpes simplex virus, Vesicular stomatitis virusTumorigenic: NoAge: embryo; 14 to 17 day gestationThe BALB/3T3 clone A31 is one of several cell lines developed by S.A. Aaronson and G.T. Todaro in 1968 from disaggregated 14- to 17-day-old BALB/c mouse embryos. The cells are extremely sensitive to contact inhibition of cell division, grow at a high dilution, exhibit a low saturation density and are highly susceptible to transformation in tissue culture by the oncogenic DNA virus SV40 and murine sarcoma virus.

5.中止反应 加2ul 0.2M EDTA (pH 8.0) 和/或 65度 水浴 10分钟
二、标记效率检测
(一) 试剂配置
Solution Composition Preparation
Washing buffer 0.1 M Maleic acid, 0.15 M NaCl; pH 7.5 (20° C); 0.3% (v/v) Tween 20
Maleic acid buffer 0.1 M Maleic acid, 0.15 M NaCl; adjustwith NaOH (solid) to pH 7.5 (20° C)
Detection buffer 0.1 M Tris-HCl, 0.1 M NaCl, pH 9.5 (20° C)
