The Swarm calibration/validation phase will be a valuable learning experience to better control the intrinsically different information content and contamination errors of the vector and the gradient data.
About 400 positive clones were selected randomly and amplified using M13 primers (forward and reverse) after removal of contamination from the vector and primer sequence.
Any vector contamination of the public ESTs/mRNAs was removed using the seqclean program [ 39].
First, contamination of cloning vectors in the EST sequences was compared in 42,901 ESTs (23,684 ESTs in phage libraries and 19,217 in plasmid libraries) using in-house BLAST, as described above.
The plasmid library is excellent from the viewpoint of contamination of vector sequences and host bacterial genome sequences.
Indirect transmission occurs via vectors, i.e. mosquitos, by contamination of the environment through faecal shedding [ 2] or by consumption of venison [ 3].
BLAST evaluation of the performance of the vector trimming (Tables 2 and 3) confirmed that the vector re-linearization step turned SeqClean into an ideal tool for removal of vector contamination from automated sequencing data.
Identify the magnitude of the vector.
Vector A + Vector B = Vector B + Vector A. To subtract, add the "negative" of the vector.
This facilitates ligation into cloning vectors for library construction and reduces concatamerization artefact contamination of the final cDNA sample.
