In he - 3 and de - 3 , 16 protein spots that were absolutely different ( only expressed in diploid embryos but not in haploid embryos or vice versa ) and 16 protein spots that were up - and down - r gulated were identified unambiguously . in he - 2 and de - 2 , 20 protein spots that were absolutely different ( only expressed in diploid embryos but not in haploid embryos or vice versa ) and 5 protein spots that were up - and down - regulated were identified unambiguously , some of these different proteins are correlative with eyes development , nerve development , development regulation , cell differentiation and maintenance , arthromere formation and signal transduction . it shown that gene expression have significant difference between diploid and haploid during embryos developing 分别选取其中70个分辨好的差异蛋白质点进行原位胰蛋白酶酶解,酶解的肽片段用基质辅助激光解析电离分行时间质谱( maldi - tofms )得到肽质指纹图谱,再在网上peptident软件中搜索swiss - prot和trembl数据库,初步鉴定了he - 3和de - 3上32个差异蛋白质点,其中包括16个表达量上有差异的蛋白质点( p 0 . 05 )和16个有无表达的差异蛋白质点,并且初步鉴定了he - 2和de - 2上25个差异蛋白质点,其中包括5个表达量上有差异的蛋白质点( p 0 . 05 )和20个有无表达的差异蛋白质点。
