This product is specifically designed for human MII-stage oocytes and embryos at various developmental stages. It employs a classic HEPES-M199 buffer system to ensure precise stability of osmolarity and pH during thawing. The formulation maintains a scientifically optimized ratio of ethylene glycol and dimethyl sulfoxide as core cryoprotectants, achieving efficient vitrification while significantly reducing cytotoxicity. This preserves embryonic developmental potential and enhances post-thaw viability. Human serum albumin (HSA) is specifically incorporated to provide nutritional support for cell membrane repair. The entire product line is free from antibiotics such as gentamicin, completely eliminating the risk of antibiotic exposure.
