NIP-OVAL (Ovalbumin)

4-Hydroxy-3-iodo-5- nitrophenylacetyl hapten is conjugated to OVAL protein through lysine by amide bonds.


Biotin O-Succinimide is conjugated to 4-Hydroxy-3-iodo-5-nitrophenylacetyl-Bovine Serum Albumin.


Fluorescein is conjugated to PC-BSA. This product is homologous to PC-BSA and is most useful in cell cytometry.

PC-HPA-BSA (Bovine Serum Albumin)

Phosphorylcholine hapten is coupled to p-hydroxyphenylacetic acid through azo linkage; this moiety then coupled to BSA carrier via water soluble carbodimide conjugation.

Hapten Reagents

Hapten reagents, such as succinimide esters, allow you to synthesise your own custom conjugates. LGC, Biosearch Technologies offers several combinations of haptens, proteins and other tags and conjugates so you can get the exact immunochemical you need. 

In our immunochemicals portfolio, you can also find unlabelled proteins, hapten-FICOLL conjugates and haptens with various spacers (e.g., caproic acid, hexyl, aminocaproic, etc.) that are ready to conjugate to your protein of interest.
