“I am using the XYClone to drill the zona pellucida of both human and mouse oocytes or zygotes. It is very fast, offers reliable zona drilling and makes nuclear transfer very convenient. The XYClone is a great tool that works well with other tools and methods, including the piezo drill. With improved objectives, it is now possible to perform all manipulations with the laser objective.” Download PDF of Testimonial

“The laser-assisted injection of 8-cell stage mouse embryos has allowed us to generate fully ES cell-derived F0 mice (VelociMice) in high yield using inbred or hybrid ES cells. Last year we generated about 200 lines of mice. The use of the XYClone Laser System has made our process much more efficient and has resulted in phenotypable F0 mice at dramatically lower mouse costs.” Thomas DeChiara

View CV (PDF) "Laser technology is very essential for isolation of human ES cells because it eliminates the use of animal product, such as antibodies for immunosurgery, and allows very precise separation of ICM from trophoblast, maintaining the intactness of inner cell mass. It is essential for xenofree ES cells." (Download PDF of testimonial)

The XYClone laser has been of huge benefit to developing our technique of human somatic cell nuclear transfer. Prior to using the XYClone we were relying on traditional enucleation procedures to remove the genetic material from human oocytes. This generally requires piercing through the elastic outer protein shell of the egg by using a microscopic beveled glass pipette, which often induced damage and resulted in lysis of the egg. The elasticity of the human zona pellucida compared with other species remained a challenge. However, following installation of the XYClone laser objective, we have been able to speed the process of enucleation to a matter of seconds, without eliciting damage to the egg. The XYClone laser suitably makes a very small, neat slit in the zona pellucida which facilitates the DNA removal. We have been very impressed by how it has dramatically improved our enucleation efficiency and reduced the lysis rates of the eggs. It has also been incredibly easy to operate and we love how easy it is to target the site of interest using the software provided. It appears to be an extremely powerful tool that has improved our ability to create human cloned embryos for the purposes of deriving patient specific stem cell lines which may one day be used to treat non-curable diseases.
