Sodium azide NaN3 is often used to prevent antibody degradation in 0,02% W/V concentrations. MyBioSource supplies azide free antibodies on request.Recently MyBioSource made this Papilloma Virus, 16, Early Protein 7 (hPV) (BSA )[Papilloma Virus, 16, Early Protein 7] available without azide. It will stick less and is more suitable for ELISA or in vivo studies. However you need to store the @[email protected] frozen and ship on dry ice.
Human proteins, cDNA and human recombinants are used in human reactive ELISA kits and to produce anti-human mono and polyclonal antibodies. Modern humans (Homo sapiens, primarily ssp. Homo sapiens sapiens). Depending on the epitopes used human ELISA kits can be cross reactive to many other species. Mainly analyzed are human serum, plasma, urine, saliva, human cell culture supernatants and biological samples.
