Hapten

2-(N-Phthalimidoylmethylthio)acetic acid (MFA) is a hapten with a carboxyl group at the end of its spacer arm, suitable for reacting with free amine groups of proteins. 2-(N-Phthalimidoylmethylthio)acetic acid can be combined with carrier proteins and used in antigen design.

6-(N-Phthalimidoylmethylthio)hexanoic acid (MFH) is a hapten with a carboxyl group at the end of its spacer arm, suitable for reacting with free amine groups of proteins. 6-(N-Phthalimidoylmethylthio)hexanoic acid can be combined with carrier proteins and used in antigen design.

6-[(4-Oxo-1,2,3-benzotriazin-3-yl)methylthio]hexanoic acid (MBH) is a hapten with a carboxyl group at the end of its spacer arm, suitable for reacting with free amine groups of proteins. 6-[(4-Oxo-1,2,3-benzotriazin-3-yl)methylthio]hexanoic acid can be combined with carrier proteins and used in antigen design.

2-[(4-Oxo-1,2,3-benzotriazin-3-yl)oxy]acetic acid (HBA) is a hapten with a carboxyl group at the end of its spacer arm, suitable for reacting with free amine groups of proteins. 2-[(4-Oxo-1,2,3-benzotriazin-3-yl)oxy]acetic acid can be combined with carrier proteins and used in antigen design.

GK81 is a nicotine hapten. GK81 contains a linker attached to the 6-position of nicotine. GK81 conjugates to KLH via carbodiimide-mediated reactions.
