Application

A heterobifunctional cross-linking reagent incorporating an extended spacer with amine and sulfhydryl reactivity. Typically, coupled initially to molecules containing primary amines by amide bonds buffered at pH 7.5 (6.5-8.5) The second coupling is specific for molecules containing free sulfhydryl by thioether linkage buffered at pH 6.8 (6.5-7.0). Useful for preparation of enzyme immunoconjugates and hapten carrier molecule conjugates. Contains 9 atom linker. An extended aliphatic spacer stabilizes the maleimide prior to coupling compared to aromatic spacers.

Synthetic peptides, derived from the amino acid sequence of a Leishmania donovani clone, were used to develop an enzyme-linked immunosorbent assay (ELISA) for detecting antibodies against L. donovani. For this purpose, five peptides were conjugated to a protein carrier, human

Recently, the multipin approach for simultaneous multiple peptide synthesis was applied to the analysis of T cell determinants by using a novel cleavage method (Maeji et al., 1990). A diketopiperazine forming linker allowed cleavage of peptides into aqueous buffer which

We have previously reported that ovalbumin (OVA) coupled with liposome via glutaraldehyde (GA) induced OVA-specific- and IgE-selective unresponsiveness in mice. In this study, OVA-liposome conjugates were made using four different coupling protocols: via GA, N-(6-maleimidocaproyloxy) succinimide (EMCS), disuccinimidyl suberate (DSS)
