Neptune Sample Diluent is a non-mammalian protein-containing solution highly recommended for use with serum or plasma samples from mouse, porcine or bovine sources in an antigen-down format. It can also be used for human or other mammalian plasma samples in antibody-sandwich ELISAs.
In certain animal species, nonspecific adsorption of serum IgG to antigen coated and blocked ELISA plate surfaces is a common problem. Utilization of Neptune Sample Diluent as the serum or plasma test sample diluent will minimize the plate well adsorption of nonspecific IgGs that are always present in serum or plasma samples.
Neptune Sample Diluent contains proprietary additives in a buffered PBS base to provide an assay environment that minimizes nonspecific binding while maintaining proper ionic strength and pH for efficient antibody-antigen interaction. This diluent also contains an antimicrobial agent to provide a solution free of bacterial contamination.
