Two independent studies show that survival of pronuclear stage oocytes and cleavage stage embryos is significantly improved using FreezeKit Cleave and ThawKit Cleave.
Significantly higher blastocyst survival
Two clinics in Sweden made a pre-clinical, randomised comparison of FreezeKit Cleave and ThawKit Cleave with an existing commercial product for freezing of cleavage-stage embryos.
The primary endpoint was blastomere survival rate. A statistically significant difference in blastomere survival was seen between the two methods.
Significantly better survival rate
At Westmead Fertility Center Australia, clinical use of FreezeKit Cleave and ThawKit Cleave resulted in improved survival. A retrospective analysis on 1497 embryos from 377 patients showed significantly better survival rate for both 2PN- and cleavage-stage embryos.
Safe to use for previously frozen material
Survival of cleavage-stage embryos frozen with our older product, FREEZE-KIT 1, and thawed with the new ThawKit Cleave was 73%. This demonstrates the safety of the new procedure on previously frozen material.
Learn how to use FreezeKit Cleave and ThawKit Cleave
New media composition
MOPS-buffered for more stable pH during handling and temperature shifts.
Based on our G-Series™ media with carefully selected amino acids for embryo metabolism.
Hyaluronan and Human Serum Albumin are included for cryo protection.
Improved levels of cryoprotectants in freezing kit for better dehydration.
PrOH not present in the thawing media for reduced exposure time to penetrating cryoprotectant.
Time-saving and convenient
FreezeKit Cleave and ThawKit Cleave make the whole slow freezing procedure faster and more convenient. Fewer steps compared to current protocol save time, but also reduce operator variability and facilitates the process of training new staff. Most importantly is however that the fewer steps and shorter handling time lower the stress induced to the embryos.
