hi everyone

we have been trying to clone a DNA fragment which has been double digested with EcoRI and XhoI (276 nt) and purified after gel electrophoresis into pBbB6c-GFP for months now, to no avail. usually after colony PCR, we see fragments that are around 300 nt longer than what we expect. we use pBRevBam and GGTGAGCCAGTGTGACTCTAG as forward and reverse primers for colony PCR.

has any one any experience with this vector?
