特异性

We tested whether inhibitory GABAergic synaptic transmission regulates Xenopus optic tectal cell dendritic arbor development in vivo by expressing a peptide corresponding to an intracellular loop ofthe gamma2 subunit of type A GABA receptors GABA(AR, which is required to anchor GABA receptors to the postsynaptic scaffold.

我们想证明如下设想：抑制性GABA能突触传递是否能调节早蟾视顶盖细胞的树突发育。因为GABA受体的gamma2亚基有一段细胞内的跨膜端序列，这段序列对锚定GABAA受体到突触后膜是必须的，所以我们的主要方法是设计了一段特异性的争对细胞内段的序列，这样就特异性的阻断了单个细胞GABA能的突触传递。

On other hand, specific fragments containing thermostable DNA polymerase gene were amplified from the genomic DNA of some strains of thermophilic bacteria isolated from Yunnan hot springs, and recombinant plasmids were constructed.

The efficiency of selection was monitored by comparing the number of phage recovered from the acid elution and cell lysate in each round,and by testing EGFR binding specificity of polyclonal phagescFv on CHOEGFRGFP1 and CHOK1 cell with cell ELISA. Bacterial PCR was used to select clones containing a 1 kb insert. Cell ELISA was used to determine EGFR binding specificity of monoclonal pscFv on EGFR positive and negative cell. The number of individual EGFRbinding clones was determined with nucleotide sequencing. Results 500fold enrichments were observed by tittering phages in the cell lysate after five rounds of selection.

以稳定转染的CHOEGFRGFP1细胞和未转染的CHOK1细胞分别作为EGFR阳性和阴性细胞，采用负筛选的方法进行筛选；通过比较每轮投入及洗脱出噬菌体的效价比以及细胞ELISA检测多克隆pscFv与阳性、阴性细胞结合情况对筛选过程进行监测；采用菌落PCR挑选含有全长scFv片断的菌落，进一步用细胞ELISA检测单克隆pscFv与EGFR阳性及阴性细胞结合特异性；挑选EGFR特异性单克隆pscFv采用DNA测序法确定克隆多样性。

Results 500fold enrichments were observed by tittering phages in the cell lysate after five rounds of selection. A signal significantly greater than background binding was observed from the third to the fifth round of selection on CHOEGFRGFP1 and CHOK1 cell, but a part of polyclonal scFv bound EGFR specially. About 45% of the selected clones contained a fullsized insert of 1 kb. One unique human antiEGFR scFv (F4scFv) was isolated by analyzing with cell ELISA and DNA sequencing.

结果 经过5轮筛选，细胞裂解液中洗脱出噬菌体效价有500倍以上增长；细胞ELISA结果显示多克隆pscFv与CHOEGFRGFP1细胞和CHOK1细胞均有明显结合，但有部分特异性结合EGFR；菌落PCR显示约45％克隆中含有完整的1kb scFv片断；经细胞ELISA、 DNA测序检测共获得1株EGFR特异性单链抗体，命名为F4scFv。
