Nov 28, 2023 · The Basic Local Alignment Search Tool (BLAST) finds regions of local similarity between sequences. The program compares nucleotide or protein sequences to sequence databases and calculates the statistical significance of matches.
Select the sequence database to run searches against. No BLAST database contains all the sequences at NCBI. BLAST databases are organized by informational content (nr, RefSeq, etc.) or by sequencing technique (WGS, EST, etc.). more...
Did you know NCBI’s PubChem is the world’s largest collection of freely accessible chemical information? You can search chemicals by name, molecular formula, structure, and other identifiers, as well as find chemical and physical properties, biological activities, safety and toxicity information, patents, literature citations and more.
ElasticBLAST starts instances for you, provisions them with BLAST software and loads the BLAST database you requested. ElasticBLAST runs your batches on the instances, queuing up the work with cloud native scheduling software (Kubernetes on GCP and AWS Batch on AWS).
The program compares nucleotide or protein sequences to sequence in a database and calculates the statistical significance of the matches. This chapter first provides an introduction to BLAST and then describes the practical application of different BLAST programs based on the BLAST Quick Start mini-course (www.ncbi.nlm.nih.gov/Class/minicourses).

Local alignments algorithms (such as BLAST) are most often used. A global alignment should only be used on sequences that share significant similarity over most of their extents, and then it will sometimes return a better presentation.
NCBI BLAST allows you to input a sequence from DNA, RNA or protein residues (amino acids) and find sequences that are identical or similar. To get to BLAST from the NCBI home page, click BLAST from the Popular Resources menu bar on the right of the page.
BLAST Highlights. NCBI has recently designed the BLAST interface to improve usability. New features include: A list of search results performed within the past 36 hours; Search strategies that can be saved to MyNCBI; Reorganized home-page links to BLAST forms; Redesigned BLAST forms with usability enhancements; A documentation catalog; Common ...
BLAST is a computer algorithm that is available for use online at the National Center for Biotechnology Information (NCBI) website, as well as many other sites. BLAST can rapidly align and...
