Abstract: 1438151 Polymeric carriers for enzymes CESKOSLOVENSKA AKADEMIE VED 7 Aug 1973 [18 Aug 1972] 37427/73 Headings C3H and C3P Polymeric carriers for biologically active compounds, e.g. enzymes, are obtained by reacting together (A) the surface of a primary carrier containing reactive groups, which carrier is either a naturally occurring three-dimensional polymer such as wool, silk or collagen, or a water-soluble three-dimensional synthetic polymer derived at least in part from a bi- or multifunctional monomer, and (B) a secondary carrier which is a water-soluble linear polymer containing reactive groups complementary to those of the first carrier and also containing, either initially or by subsequent reaction, active ligands able to bind a biologically active compound. In examples, (1) a primary carrier comprising a hydrolysed and diazotized hydroxyethyl methacrylate/ethylene glycol dimethacrylate/2 - (p - acetaminophenoxy)ethy] methacrylate copolymer is reacted with a secondary carrier comprising a diethylene glycol monomethacrylate/2 - (p - acetaminophenoxy)ethyl methacrylate, and subsequent to reaction the remaining diazo groups on the primary carrier are coupled with #-naphthol, and the secondary carrier is then diazotized; (2) similar to (1) except that after the reaction of the primary and secondary carriers the aminophenyl groups of the latter are mercurated with mercuric acetate; and (3) a primary carrier comprising a hydroxyethyl methacrylate/ethylene glycol dimethacrylate/methacrylanilide copolymer is reacted with a secondary carrier comprising a diazotized diethylene glycol monomethacrylate/2 - (p - acetaminophenoxy) ethyl methacrylate copolymer. Chymotrypsin is bound to the products of above Examples 1 and 3, and papain to the product of Example 2.

[Class 98 (ii).] The invention of the parent Specification, in which pictures produced on films having longitudinal lenticular elements are produced by contact printing without watering by causing the original and the copy film to slide laterally over each other in the printing gate so as to produce a relative displacement of the films equal to the width of a lenticular element during a feed movement of the films equal to the height of the printing gate, is applied to the reproduction of pictures produced on films having transverse lenticular elements by causing the films to slide longitudinally over each other in the printing gate to produce a similar relative displacement. The sliding movement may be produced as by employing original and copy films having feed perforations of slightly different pitch, or by employing pinions of slightly different diameters for feeding the two films through the printing apparatus. The slight inclination to each other given to the films in the process of the parent Specification is unnecessary in the present invention.
