    在从胡萝卜愈伤组织细胞中分离出两个与重力作用相关的酯酶(grEST1 和grEST2)后( 蔡伟明等1998) ,对这两个酯酶的性质作了进一步研究。
    The callus subcutured on MS + 0. 5 mg/L 2,4-D+0. 2 mg/L 6-BA grew well and formed green-thick callus. The callus cells were mostly diploid,a few sub-diploid and other ploidy cells.
    愈伤组织继代增殖的最佳培养基为MS+0.5mg/L 2,4-D +0.2 mg/L 6-BA,在其上继续生长,形成淡绿色、致密的愈伤组织,愈伤组织细胞主要为二倍体,也有少量的亚二倍体细胞和其它倍性细胞产生。
    The pBIFN was transformed into Agrobacterium tumefaciens strain LBA4404. Then hIFN-α2b gene was introduced into Ginseng callus cells via Agrobacterium-mediated transformation.
    用冻融法将pBIFN导入根瘤农杆菌LBA4404,经卡那霉素和利福霉素筛选后利用农杆菌介导的转化法将hIFN-α2基因导入人参愈伤组织细胞
    Results:Stable integration of the hIFN-α2b gene in the Ginseng callus cells′ genome was confirmed by PCR analysis.
    结果:经PCR检测表明hIFN-α2b基因已成功整合到人参愈伤组织细胞基因组中。
