Features & Benefits

Understanding the oocyte is critical to understanding embryogenesis, and studies show that an oocyte’s disrupted spindle apparatus or a weakened zona pellucida can yield lower pregnancy rates. In fact, studies show that pregnancy is up to 8 times more likely when the inner zona pellucida is well-ordered.

Unprecedented Resolution

  • High-contrast live images of the oocyte and spindle

Non-invasive Imaging

  • Does not require the use of any labels or stains

Quantitative Analysis

  • Ability to track oocyte behavior over time and record data points of molecular density and orientation

Proven

  • Successfully used to image many different mammalian species for both enucleation and developmental studies

Reporting Capability

  • Collected sample data can be organized into an intuitive, exportable report

Easy Integration with Small Footprint

  • Fits most inverted microscopes with simple installation process

Adding Oosight to your lab can improve oocyte quality grading success by providing a quantitative and reproducible method to measure biological disruption within the oocyte. The Oosight provides measurements of molecular order and alignment of birefringent structures including: the spindle, zona pellucida, and oolemma.

Improve the efficiency of cryopreservation

The Oosight helps verify vital structural bodies in the oocytes are intact after undergoing freezing procedures.

Nuclear Transfer (SCNT)- No Staining Needed

With Oosight, you can remove the spindle in nuclear transfer techniques without using Hoechst dye DNA staining and minimize damage to vital cytoplasmic organelles.

Software

Oosight can help identify oocytes that may have been falsely labeled MII due to conventional imaging techniques. The system can also help screen for oocytes with highly disrupted spindles, such as those that are multi-polar.

In a conventional contrast image (left) of a human MII oocyte taken just prior to ICSI, structures such as the spindle and multiple layers of the zona pellucida remain invisible. In an Oosight image (right) the spindle is clearly seen to be nicely barrel shaped and the three layers of the zona pellucida are all visible.

Oosight software visualization tools include (left to right): slow-axis orientation color map, orientation vector overlay, retardance color map, automated SpindleFinder™, and automated ZonaFinder™.

With unprecedented resolution and calibrated setup, Oosight software helps improve your grading routine with reproducibility and the speed needed for micromanipulation.

Choose between the Oosight Basic vs Oosight Meta system.

Oosight Basic

The Oosight Basic imaging system combines patented optical, electronic and software elements to produce both live and still images of critical structures within the oocyte, including the meiotic spindle and tri-laminar zona pellucida.

Oosight Meta

The Oosight Meta imaging system combines the image capture capability with additional analysis tools such as automated SpindleFinder™, automated ZonaFinder™, reporting, and Movie Capture to make quantitative, reproducible oocyte analysis possible.
