An index of general molecular biology techniques used in studies of S. purpuratus
Arrayed Filter Manual
The techniques used to hybridize probes to arrays of cDNAs on filters are detailed here. The manual is based on pages from the RZPD with modifications installed at Caltech.
Non-radioactive library screening protocol
The availability of sensitive chemiluminescent detection systems for hybridization screening of arrayed library filters now makes it possible to reach outcomes similar to methods using 32P labeled probes. We have used a digoxygenin based protocol with good success. It is detailed here.
Subtractive Probe Analysis
Our techniques for complex probes to be used on arrayed filters for gene discovery have been perfected by Jonathan Rast in the Davidson Laboratory. The investigation underlying this work is published: Rast J. P. et al, Developmental Biology 228 (2): 270-286, 2000. Supplementary data is presented here, as well.
Additional Notes on cDNA Library Preparations
The procedures used to construct the cDNA libraries are described here.
The Reporter Plasmid, EpGFPII
The sequence and map of the reporter construct described in: R. A. Cameron, P. Oliveri, J. Wyllie, and E. H. Davidson (2004) cis-Regulatory Activity of Randomly Chosen Genomic Fragments from the Sea Urchin. Gene Expression Patterns 4, 205-213 can be found here.
BAC Library Vector
The BAC vector pBACe3.6 is the one we have used in the preparation of all of our macro-array genomic libraries. Constructed in Pieter J. de Jong's laboratory at the Children's Hospital Oakland Research Center, it has been used extensively for genomic libraries and sequencing projects of many species.
Fluorescent Protein Vectors
The expression of exogenous proteins in sea urchins embryos, by injection of recombinant mRNAs, is routine procedure. The Hamdoun lab has generated a vector set with the major color and tag position variants that is useful for fluorescent protein tagging and expression in urchins. The complete vector set and can be obtained here: [1]. A description of the vectors can be found in Gokirmak et al., 2012 Vectors for generation of exogenous mRNAs fused to fluorescent proteins for expression in urchins
