Abstract
1288216 Formalinized allergens D C MARSH 9 Dec 1969 [10 Oct 1968 1 Oct 1969] 48064/68 and 48189/69 Heading A5B A process for the preparation of a formilinized allergen comprises the steps of (a) removing any non-allergenic low molecular weight substances from the native allergen by a method known per se, (b) in a non- phenolic environment, incorporating the allergen with a dilute solution of formaldehyde or a formaldehyde-liberating substance, and (c) incubating the resulting product. An additive containing one or more amino. amido or guanidino functional groups capable of reacting with formaldehyde or an aminomethylol radical may also be present.
