Identification of copepod gut contents analyzed at San Francisco State University in 2013 (Food Limitation in Copepod nauplii project)

Expand/Collapse All

Description

Field collected copepod gut content sequences were identified either by comparison to our sequence library of local copepod species or using a sequence similarity approach. Sequences were Blasted using NCBI’s web_blast.pl script (http://ncbi.nlm.nih.gov/blast/docs/web_blast.pl). The Blast output was manipulated with perl scripts we wrote to isolate the accession numbers for the BLAST hits, use the accession numbers to get the full records using NCBI’s Batch Entrez (http://www.ncbi.nlm.nih.gov/sites/batchentrez), and get the taxonomic information from the full records. See nauplii_gutcontent_sequence.pdf for the output of these programs. We then compared the taxonomic information among the top 10% BLAST scores to assign the sequence to the lowest, taxonomic level shared by the top scoring hits.

Instruments

Automated DNA Sequencer

Supplied Name: Automated Sequencer

Supplied Description:

ABI 3130 Genetic Analyzer

Instrument Type

Generic Name: Automated DNA Sequencer

Acronym: Automated Sequencer

Generic Description:

General term for a laboratory instrument used for deciphering the order of bases in a strand of DNA. Sanger sequencers detect fluorescence from different dyes that are used to identify the A, C, G, and T extension reactions. Contemporary or Pyrosequencer methods are based on detecting the activity of DNA polymerase (a DNA synthesizing enzyme) with another chemoluminescent enzyme. Essentially, the method allows sequencing of a single strand of DNA by synthesizing the complementary strand along it, one base pair at a time, and detecting which base was actually added at each step.

High-Performance Liquid Chromatograph

Supplied Name: HPLC

Supplied Description:

Instrument Type

Generic Name: High-Performance Liquid Chromatograph

Acronym: HPLC

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/LAB11/

Generic Description:

A High-performance liquid chromatograph (HPLC) is a type of liquid chromatography used to separate compounds that are dissolved in solution. HPLC instruments consist of a reservoir of the mobile phase, a pump, an injector, a separation column, and a detector. Compounds are separated by high pressure pumping of the sample mixture onto a column packed with microspheres coated with the stationary phase. The different components in the mixture pass through the column at different rates due to differences in their partitioning behavior between the mobile liquid phase and the stationary phase.

Plankton Net

Supplied Description:

Mesh size 100 microns or 150 microns

Instrument Type

Generic Name: Plankton Net

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/22/

Generic Description:

A Plankton Net is a generic term for a sampling net that is used to collect plankton. It is used only when detailed instrument documentation is not available.

Thermal Cycler

Supplied Description:

Instrument Type

Generic Name: Thermal Cycler

Generic Description:

A thermal cycler or "thermocycler" is a general term for a type of laboratory apparatus, commonly used for performing polymerase chain reaction (PCR), that is capable of repeatedly altering and maintaining specific temperatures for defined periods of time. The device has a thermal block with holes where tubes with the PCR reaction mixtures can be inserted. The cycler then raises and lowers the temperature of the block in discrete, pre-programmed steps. They can also be used to facilitate other temperature-sensitive reactions, including restriction enzyme digestion or rapid diagnostics.
