For long term storage, keep the Recombinant Human Prothrombin(F2) frozen at -20 or -80 degrees Celsius. Working aliquots can be stored at +4C for a few weeks. We recommend cycles of freezing and thawing to be avoided, as they will most certainly denaturate the polypeptide chains of the protein.
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.
