microinjection

Delivering gene-editing proteins in vivo using a new strategy.

Delivering genetic technologies to appropriate cells at the appropriate times is, for many insect systems, the biggest obstacle to the widespread use of these technologies. Microinjecting developing embryos with DNA, RNA or protein remains the dominant mode of delivery in […]

Injectoporation for Gene Delivery

Let’s see.  What do we have so far? Great genomic resources?  Check. Great gene vectors?  Check. Great genome modification technologies?  Check. Effective insect genetic technology delivery systems for somatic and germ cells?  Not so much, unfortunately. Gene, transgene and RNA […]

A Collection of Methods for Editing Insect Genomes

The August 2014 issue of METHODS is devoted to the topic of “Editing and Investigating Genomes with TALE and CRISPER/Cas Systems: Genome Engineering Across Species Using TALENS” Five of the 14 protocols included in this issue are specifically focused on […]

Transgenic Honeybees – Finally!

Genome modification technologies have been increasing steadily in recent years. With the exception of direct genome editing technologies (ZFNs, TALENs and CRISPRs) variously technologies for use in insects rely heavily on transposon platforms to move these technologies into target genomes. […]

Water Fleas and Insects – Common Challenges for Genetic Modification – Shared Solutions?

The water flea, Daphnia pulex, is a microcrustacean that has become a model for biomedical research and, perhaps more significantly, a model for probing G x E (Genetics x Environment) interactions. Some genetic modification methods have been developed for Daphnia […]

Feed or Inject dsRNA in Aphids – It Depends

RNAi-based gene silencing has been reported but it has been problematic. The authors’ direct comparison of injection and feeding of dsRNA targeting the cathepsin-L gene in the pea aphid, Acyrthosiphon pisum. Single aphids were analyzed at the level of five […]

Spider Genomes Sequenced

The assembled genome of the social velvet spider and a draft assembly of the tarantula genome that represent two major taxonomic groups of spiders was reported. The genomes are large and intron length is long and exons are small. Interesting […]
