The insert should be 0.9 kb, which is correct on oagarose gel
electrophoresis analysis. However, after ligation, tranformation. Positive
transformants show plasmid (correct size( and insert (1.5 kb instead 0.9 kb)
. Then we expressed it and do not get the protein. Any suggstion? Thanks

既然知道插入的片段大小不对,怎么还进行下面的表达?首先测序列呀。你可以试一下
这个公司的DNA片断和PCR纯化KIT。可以提高克隆效率,便宜而且好用

You should sequence the constructs, at least, to make sure that the ORF is
correct (with start and stop codons).
