We are talking about the NFL here folks, we dont want any gaps in the protection schemes
Its defined structure and receptor selectivity make it ideal for controlled experimental models focused on studying endocrine pathways
thereafter, 50 ml of precultures were induced with 450 ml of expression medium (10 g l 1 yeast extract (Gibco, 212750), 20 g l 1 bacto peptone (Gibco, 211677), 20 g l 1 d-galactose (Panreac, A1131), 67 mM potassium phosphate monobasic buffer pH 6.0 (Thermo Scientific, 424200250), 25 g l 1 ethanol (Scharlau, ET00062500), 2 mM copper sulfate (Merck, C7631) and 25 g ml 1 chloramphenicol (Merck, C0378)) in a 2.5-l baffled flask (Quimigen, 931136-B) (OD 600 = 0.1)
Furthermore, copper ions can interact with oxygen by catalyzing Haber-Weiss and/or Fenton reactions
