If you buy Antibodies supplied by bioassay they should be stored frozen at - 24°C for long term storage and for short term at + 5°C.E05 478 566 350 170 or Enzyme-Linked Immunosorbent Assays,E05 478 566 350 170 or Enzyme-Linked Immunosorbent Assays,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.Immunoglobulin M, or IgM for short, is a basic antibody that is produced by B cells. IgM is by far the physically largest antibody in the human circulatory system. It is the first antibody to appear in response to initial exposure to an antigen
