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 Addgeneās 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.

For protein expression. A. gambiae deoxynucleoside kinase. Phosphorylates a wide variety of nucleosides at the 5-hydroxyl position. Pet28a plasmid, KAN resistant, N-terminal TEV-cleavable 6xHis tag.
tRNA synthetase/tRNA pair for the in vivo incorporation of N6-(trifluoroacetyl)-L-lysine (TFA-Lys) into proteins in E. coli in response to the amber (TAG) codon
The encoded protein is the anti-HA scFv (anti-HA frankenbody) fused with the mEGFP and His-tag. This plasmid is for bacteria protein expression under T7 promoter and protein purification with HisTrap.
Bacterial expression plasmid used for T7 promoter driven expression of recombinant proteins with N-terminal 8X His, thrombin cleavage site, SUMO, and TEV cleavage site.
This plasmid encodes an engineered oxygen-independent flavin binding fluorescent protein with N-terminal 6xHis tag. Its quantum yield is improved compared to wild type.
This plasmid encodes an engineered oxygen-independent flavin binding fluorescent protein with N-terminal 6xHis tag. Its quantum yield is comparable to EGFP.
