Chitin hexamer was conjugated to mono-BOC-diaminoethane, gamma -aminobutyri
c acid or glycine using reductive amination. Each hapten was conjugated to
ovalbumin (OVA) or mouse serum albumin (MSA) for immunization and immunoass
ay, respectively. Serum from a mouse immunized with the diaminoethane conju
gate, demonstrated competition with chitins in a modified indirect immunoas
say.
