This product is a specialized vitrification solution designed for human MII-stage oocytes and embryos at all developmental stages. Its core formulation relies on the classic HEPES-M199 buffer system, providing an exceptionally stable and reliable physicochemical environment throughout the entire cell handling process. The product innovatively employs a combination of ethylene glycol and dimethyl sulfoxide (DMSO) as highly effective, low-toxicity vitrification protectants. This formulation significantly reduces cryopreservation-induced cellular damage, thereby substantially improving post-thaw cell viability and developmental potential. Human serum albumin (HSA) is specifically incorporated into the formulation to deliver essential nutritional support and membrane protection for cells. Notably, this product is entirely antibiotic-free (contains no gentamicin), eliminating potential antibiotic risks and providing a safer, antibiotic-free culture environment for assisted reproductive technologies.
