user-defined upper limit for the number of target sequences returned
Alignment
region of similarity between target and query sequences
E-value
a BLAST statistic representing the significance of an alignment, values close to zero
indicate high sequence similarity with low probability of the similarity occurring by chance
Identities
the number of exact nucleotide matches over the alignment, expressed as a fraction
and a percentage
Query Coverage
the length of the query sequence that matches the target sequence in the
alignment
Bit Score
a BLAST statistic measuring the quality of an alignment, higher values indicate a
more significant match
Span
the length of the alignment, including gaps
About Search by Sequence
Search by Sequence performs a nucleotide-nucleotide BLAST search against Addgene’s plasmid sequence database.
BLAST returns plasmids with similarity to the query sequence.
Results are sorted by E-value, a statistic from BLAST that describes the significance of a match.
Lower values are considered better matches.
FASTA headers and numbers at the beginning of each line will be removed.
The query should only contain DNA characters.
The minimum query length is 30 nucleotides. Support for short sequence queries is under development.
Tips for Success
Inspect the percent identity, query coverage, and alignment details to determine if a result match is satisfactory.
Visit the corresponding plasmid webpage to view additional details about a matching plasmid.
If no results are returned, try a different isoform or region of the desired sequence. There may not be a match in our database.
You can adjust the Max Results setting on the results page from 25 to 500. If many sequences share the same top E-value,
only a truncated set of equally high-scoring matches will be shown. Set the Max Results to 500 to see more matches.
