              Effects of β-mercaptoethanol on in vitro maturation and 
              glutathione level of buffalo oocytes, Veterinary World 
              8(2):213-216. 
 
              Abstract 
 Aim:
              The present study was carried out to evaluate the effect of 
              supplementation of β-mercaptoethanol (β-ME) on in vitro maturation 
              rate and glutathione (GSH) level of buffalo oocytes. 
              Materials and Methods: Oocytes were recovered from buffalo’s 
              ovaries collected from government approved slaughter house (near 
              Kamela darwaza, Surat) of Surat Municipal Corporation. The 
              obtained oocytes were in vitro matured in maturation media 
              supplemented with 0 μM (117 oocytes), 100 μM (46 oocytes) and 200 
              μM (42 oocytes) concentration of β-ME. After 24 h of incubation, 
              maturation rate of oocytes and intra-cellular GSH level were 
              determined. 
              Results: The results showed that the presence of β-ME did not 
              influence (p>0.05) the oocyte maturation rate. However, GSH level 
              increased significantly (p<0.05) in matured oocytes when 
              supplemented with 100 μM and 200 μM β-ME (6.19±0.10 and 6.37±0.20 
              pmol/oocyte) as compared to control media (4.68±0.26 pmol/oocyte). 
              Conclusion: It was concluded that β-ME may have a potential to 
              increase the meiotic maturation of in vitro cultured oocytes and 
              protect it from oxidative damage. 
              Keywords: buffalo oocytes, in vitro maturation, β-mercaptoethanol, 
              glutathione.
