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.
Tips for Success
Enter a distinct sequence that is an important, differentiating feature. For example, the coding region of
a gene, instead of the plasmid origin of replication.
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.
Choose a different BLAST database. Try the general “All Addgene Plasmids” (default selection),
instead of a specific database, such as “Plant Expression Plasmids”
Try selecting a different BLAST algorithm:
megablast: Designed for comparing sequences within the same, or closely related, species.
Default selection.
blastn: Designed for comparing sequences from different species. May return additional results,
if exact species match is not required.
blastn-short: Optimized for searching with shorter sequences (<= 30 nucleotides)
but can still be effective with slightly larger sequences.
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.

pET-21b(+) based plasmid for expresion of MHETase (Genbank GAP38911.1) linked to PETase (Genbank GAP38373.1) from Ideonella sakaiensis by a 12 residue Gly/Ser linker; codon optimized for expression in E. coli K12, with C-terminal His tag.
Ready-to-use AAV2 particles produced from pENN.AAV.CMVs.Pl.Cre.rBG (#105537). In addition to the viral particles, you will also receive purified pENN.AAV.CMVs.Pl.Cre.rBG plasmid DNA.
CMV-driven Cre. These AAV preparations are suitable purity for injection into animals.
PylRS (AF)/tRNA Pyl orthogonal pair for genetic code expansion that allows site-specific incorporation of noncanonical amino-acids into a POI using the Amber stop codon
pRepCap6 contains both rep and cap genes from the AAV6 genome, but lacks the viral terminal repeats (Rutledge et al., 1998). It lacks adenovirus helper functions required for stock production.
To fuse your protein of interest to the C-terminus of BioID2 and use in proximity-dependent biotin identification (BioID); MCS is present downstream of myc tag and BioID2 tag
Ready-to-use AAV8 particles produced from pAAV-nEF-Con/Foff 2.0-ChRmine-oScarlet (#137161). In addition to the viral particles, you will also receive purified pAAV-nEF-Con/Foff 2.0-ChRmine-oScarlet plasmid DNA.
nEF-driven expression of ChRmine-oScarlet in the presence of Cre (inhibited in the presence of Flp). These AAV preparations are suitable purity for injection into animals.
Modified version of lentiSAM v2, a lenti sgRNA cloning backbone with MS2 loops at tetraloop/stemloop 2, dCas9-VP64, and puro resistance marker. Contains BsmBI sites for insertion of spacer sequences.
This plasmid contains human codon optimized sequence of mitoLbNOX which is a water-forming NADH oxidase that can be used to increase NAD+/NADH ratio in mammalian cells.
