Oosight system
In addition to having micromanipulation and microinjection equipment that allows us to inject sperm into the cytoplasmic cavity of the oocyte (ICSI). One of these microinjectors has a built-in Oosight system implemented which allows us to non-invasively (without adding dyes) precisely observe the location of the mitotic spindle indicative of the correct development and optimal degree of maturation of the oocyte. This facilitates the selection of the most suitable oocyte for the ICSI or IMSI procedure. In addition, Oosight IS indicates the insertion site of the sperm inside the oocyte so as not to damage sensitive cytoplasmic structures.
Customer benefits
Having these micromanipulation and microinjection equipment that incorporates the Oosight system to evaluate the quality and degree of maturation of the oocytes allows us to offer this service to embryologists who wish to train in this technique and acquire the necessary skills to be able to carry out carry out this Technique in the human clinic. Furthermore, the implementation of this oosight imaging system allows them to become familiar with the internal structures of the oocyte and classify it according to its level of development, learning to differentiate which are the most optimal oocytes to later perform ICSI or IMSI. This equipment and the oosight system
It allows the practical training of students of master’s degrees and specialization courses in human or animal assisted reproduction.
Because our laboratory is one of the few that researches assisted reproduction with animal models and has all this equipment, human reproduction clinics that want to perform tests with animal oocytes or embryos can perform their tests.
In our laboratory, since experiments can only be carried out on animal species, our laboratory is suitable for it. In addition, the studies can also be carried out under regulatory requirements, since the institution that performs them is certified in Good Laboratory Practices.
In this way, preclinical studies can be carried out in animal models in compliance with the strict guidelines of the regulatory agencies, ensuring the reliability and traceability of all the results and tests carried out in its different services.
Target customer
This service can provide assistance and service to all those Human Reproduction companies and clinics that want to carry out in vitro fertilization studies using Micromanipulation and microinjection techniques of mouse embryos or other animal species, since we have a piezoelectric system that facilitates this process. without damaging the oocyte. In addition, they can carry out studies that allow visualization of the internal structures and location of the mitotic spindle, which will allow them to select those oocytes that present the best morphology and are fully mature to be fertilized later.
