Application

Recommended for manipulation of mouse embryos at ambient temperature. M2 and M16 Medium are common media for in vitro culture of preimplantation stage embryos. It is a modified Krebs-Ringer bicarbonate solution, which is very similar to Whitten′s Medium. M16 contains pyruvate and lactate as energy sources since preimplantation embryos do not utilize glucose efficiently.

M2 Medium is a further modification of M16 that substitutes HEPES buffer in place of some of the bicarbonate. M2 is used for collecting and handling embryos for prolonged periods outside a CO2 incubator.

Quality

Presence of particulates in solution will not affect product′s performance.

Reconstitution

Supplement with 0.06 g/L potassium penicillin-G and 0.05 g/L streptomycin sulfate.

Analysis Note

This product is tested for its ability to support the development of one-cell mouse embryos to expanded blastocysts. Minimum requirement is 80% development to blastocyst.

Embryonic diapause is a common reproductive strategy amongst mammals, requiring an intimate cross-talk between the endometrium and the blastocyst. To date, the precise molecular signals responsible are unknown in the mouse or any other mammal. Previous studies in the mink

Methionine adenosyltransferase II (MAT2A) is essential to the synthesis of S-adenosylmethionine, a major methyl donor, from L-methionine and ATP. Upon fertilization, zygotic genome activation (ZGA) marks the period that transforms the genome from transcriptional quiescence to robust transcriptional activity. During

The paternal environment is thought to influence sperm quality and future progeny may also be impacted. We hypothesized that prenatal exposure to environmentally-relevant contaminants impairs male reproduction, altering embryo gene expression over multiple generations. Folic acid (FA) can improve sperm

Cumulus cells (CCs) are considered as an important source to predict oocyte quality. Despite numerous candidate genes in CCs have been identified for embryonic developmental competence, the results are inconsistent. The next generation RNA-sequencing was used to investigate the transcriptomic

Mutations in PARK2 (parkin) can result in Parkinson's disease (PD). Parkin shares a bidirectional promoter with parkin coregulated gene (PACRG) and the transcriptional start sites are separated by only ~200 bp. Bidirectionally regulated genes have been shown to function in common
