Immunoglobulins

Immunoglobulins are antibodies (or parts of antibodies) used in many lab experiments. These proteins can bind specifically to antigens. In labs, recombinant immunoglobulins show up in ELISA, Western blots, flow cytometry, or as standards/controls. What’s most important is binding strength, purity, and consistency. When batches behave alike, you get better reproducibility and fewer weird results.
