Genetic Technology Delivery by Embryo Microinjection

IGTRCN Technical Course 1.0 a Great Success!

Beginning on August 17, 2015 25 scientists from laboratories of 9 countries were immersed in the theory and practice of insect genetic technologies and left at the end of the week exhausted but well trained and with a solid foundation […]

Short Course on Insect Genetic Technologies – August 2015

The Insect Genetic Technologies Research Coordination Network is offering a short course on insect genetic technologies August 17-21, 2015. Today there are myriad technologies for modifying genomes. Technologies are emerging rapidly and it is a challenge for investigators to keep […]

FlyFacility, Cambridge University. A insect genetic technologies service provider and resource

Fly Facility, University of Cambridge, UK

Insect Genetic Technologies Service Provider – Drosophila – Non-commercial Fly Facility, University of Cambridge, UK – http://www.flyfacility.gen.cam.ac.uk Our Drosophila microinjection service is available to fly researchers throughout the European Union. We can inject flies (including non-melanogaster Drosophila species) for P-element/piggyback […]

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 […]

Electroporation Theory

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 […]

Apis mellifera

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. […]

Daphnia pulex

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 […]

Feeding or Microinjecting dsRNA into Aphids for Gene Silencing.

Aphid Hemolymph and Gut Degrade dsRNA

Aphids are sap-sucking insects of great economic importance, and recently the pea aphid Acyrthosiphon pisum had its genome sequenced and annotated.  Insect genetic technologies are in high demand for this insect but it is proving to be a real challenge. […]

Germ-Line Transformation of Junonia coenia

Many of today’s insect genetic technologies are delivered to the germ-line of target species by direct injection of developing embryos. This is actually a major limitation to the adoption of these powerful technologies in some insect research communities– one simply […]
