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.

Allows co-translational incorporation of the fluorescent ncAA Anap directly into the target protein; expresses amber suppressor tRNA and the synthetase AnapRS
Escherichia coli plasmid with cloned regions of homology to Campylobacter jejuni chromosome flanking a NotI restriction site. pCJR01 functions as a suicide vector for integrating cloned NotI DNA.
Contains 3 genes (crtE, crtI, and crtB) of the carotenoid pathway gene cluster of Erwinia herbicola (Pantoea agglomerans) Eho10 and thereby produces lycopene in Escherichia coli
Expression of double-cysteine variant of mature phosphate binding protein, PstS, which also has a mutation to weaken phosphate binding, as scaffold for phosphate biosensor
Tier-3 vector for stable stable integration of up to three cassettes via sleeping beauty transposase including a iRFP670 marker and PuroR resistance gene (5'ITR-A1-pA::A2-pA::PRPBSA-iRFP670-p2A-PuroR-pA-3'ITR)
The burden monitor was cloned inside plasmid pAH63 [Haldimann2001]; the genome integration of the system allows the measurement of the burden imposed by synthetic constructs to Escherichia coli cells
Plpp/PlacUV5- directed synthesis of the alpha NTD fused to E. coli σ70 region 4. Used as two-hybrid control. For cloning purposes, see Addgene plasmid 53734.
The burden monitor was cloned inside plasmid pAH153 [Haldimann2001]; the genome integration of the system allows the measurement of the burden imposed by synthetic constructs to Escherichia coli cell
Tet inducible, KAN Resistant, non labelled synthesis domain of the E. coli relA gene on a low copy backbone. Used to induce controllable synthesis of ppGpp in E. coli.
