Name: X. laevis gastrula stages 10.5, 11.5 mixed Library ID: 1593 Organism: Xenopus laevis Age: 0 Stage: embryo Organ: embryo Tissue: gastrula Host: TOP10 Vector: pBluescript SK- Vector type: phagemid Insert digest: 5' EcoRI/XhoI 3' Stop Codon Status: without Description: cDNA from 2 ug polyA+ mRNA, oligo dT-primed using 5'-ACTAGTGCGGCCGCCTAGGCCTCGAGTTTTTTTTTTTTTTT-3'. Library was mass excised (from lambda-ZAPII) using ExAssist phage. The resulting single-stranded phagemids were used to infect TOP10F'. This library has been used successfully to clone a number of full-length cDNAs ranging in size from 1.4-4.5 kb. There are <0.5% clones with multiple inserts. One should be suspicious of any clone which gives 3 or more bands in an EcoRI/XhoI digest AND has an internal XhoI site. Library constructed and donated by B. Blumberg (University of California, Irvine); also referred to as Xenopus_laevis_gastrula_non_normalized.
