Hi all! In a paper of de Waal Malefyt et al. (J. Exp. Med. 1991) they´re culturing primary human blood monocytes in teflon bags from a Belgium company named Jansen MNL, St Niklaas. I wonder if anyone know if this company is still around, address ,URL´s etc, or if there´s similar products from any other company? Thanks, Mikael Englund, MSc
