Abstract The C18 juvenile hormone of insects can be dissolved in aqueous solutions up to a concentration of 2.5 - 3.0 × 10-5 M; changes in pH, buffer composition and ionic strength hardly affect this solu­bility. The hormone is salted out gradually by increasing ammonium sulphate concentrations. The juvenile hormone is bound to proteins such as bovine serum albumin or goat immunoglobulin G and can be kept in solution by these proteins up to 10-3 M. The hormone is strongly absorbed by many commonly used plastic materials but only to a lesser extent by glass and teflon.

The Stability

A fully-atomistic molecular dynamics study was performed to determine the importance of disulfide bonds on the stability of immunoglobulin G (IgG) and bovine serum albumin (BSA).The transferability of a previous prescreening methodology to assess contributions from individual disulfide bonds on conformational stability was tested on both proteins. In IgG, it was apparent that inter-chain and intra-chain disulfide bonds play different roles in maintaining structure, evidenced by clear separation of inter-chain cysteine residues upon cleavage of disulfide bonds. In BSA, a set of double disulfide bonds required both to be broken in order to observe significant structural changes, equivalently seen in a previous study of human serum albumin (HSA), a structurally similar protein. Structural analysis of IgG showed deviations in distances between domains, while analysis of BSA suggested more local structural changes. This work helps confirm the efficacy and reproducibility of the prescreening methodology on both a novel, larger protein such as IgG and a more homologous (to HSA), globular protein such as BSA. The results provide insight into the role of specific disulfide bonds in the stability of IgG and BSA.

Peroxidase Conjugate

A sensitive enzyme immunoassay for anti-β-lactoglobulin immunoglobulin G (IgG) in serum is described. Serum containing anti-β-lactoglobulin IgG was reacted simultaneously with 2,4-dinitrophenyl-bovine serum albumin-β-lactoglobulin conjugate and β-lactoglobulin-peroxidase conjugate. The complex formed from the three components was trapped onto polystyrene balls coated with anti-2,4-dinitrophenyl group IgG, eluted with ε-2,4-dinitrophenyl-L-lysine and transferred to polystyrene balls coated with anti-human IgG-γ-chain IgG. Bound peroxidase activity was determined by fluorometry. This enzyme immunoassay was 100- to 1000-fold more sensitive and more reliable than the enzyme-linked immunosorbent assay (ELISA). Anti-β-lactoglobulin IgG was detected in 91% of healthy subjects using this method.
