For short term storage NATIVE Human KININOGEN HMW DOUBLE CHAIN Protein may be kep at +4 deg. C. For long term storage keep the aliquoted vials frozen at -20 degrees Celsius.
Due to handling and transportation, small amounts of the NATIVE Human KININOGEN HMW DOUBLE CHAIN Protein may get caught on the walls or seal of the vials. Prior to use briefly rund the vial(s) through a centrifuge to collect all of the content on the bottom. Avoid freezing and thawing the vials numerous times as such cycles may denaturate the peptide chains and influence the item's performance.
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.
