Cholesterol is a component used for the preparation and study of artificial model membranes. One example is a study of valinomycin induced changes in membrane potentials of red blood cell and phospholipid (phosphatidylcholine from egg yolk plus cholesterol) vesicle suspensions. Positively charged cyanine dyes were used that fluorimetrically respond to the change in potential. Cholesterol is suitable for use in liposome preparations. It is standard for clinical work.

USP Reference Standards are specified for use in conducting official USP–NF tests and assays. USP also provides Reference Standards specified in the Food Chemicals Codex as well as authentic substances—high-quality chemical samples—as a service to analytical, clinical, pharmaceutical and research laboratories. To confirm accuracy and reproducibility, USP Reference Standards are rigorously tested and evaluated by multiple independent laboratories including USP, commercial, regulatory, and academic labs. USP also provide publicly available, official documentary standards for pharmaceutical ingredients in the USP–NF that link directly with our primary reference standards.

Sulfhydryl groups are the second most common target for modification in biological studies. They are found as exposed cysteines in protein and peptides. Sulfhydryl group biotinylation provides an advantage in some applications; for example, targeting a sulfhydryl group can help preserve the biological activity of an enzyme when amines are found at the active site.

The amine-reactive portion of SPDP reagents is the N-hydroxysuccinimide (NHS) ester. Reactions are most commonly performed in phosphate, carbonate/bicarbonate, or borate buffers at pH 7-8. Other buffers can be used provided they do not contain primary amines (or thiols or disulfide reducing reagents – see discussion of the sulfhydryl reactivity). The rate of reaction and degradation by hydrolysis increases with increasing pH; for example, the half-life of the NHS ester is several hours at pH 7 and less than 10 minutes at pH 9. NHS-ester reagents like SPDP and LC-SPDP have limited aqueous solubility and must be dissolved in organic solvent before adding them to a reaction mixture. Sulfo-NHS-ester reagents like Sulfo-LC-SPDP are water-soluble and can be added directly to aqueous reaction mixtures.
