Activity (Specifications/test method)
Determined by its ability to inhibit the IL-4-dependent proliferation of human TF-1 cells. The expected ED50 is ≤ 5.0 ng/ml (in the presence of 0.5 ng/ml of hIL-4), corresponding to a specific activity of ≥ 2 x 105 units/mg.

Reconstitution Instructions
Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to - 80°C
Handling
Centrifuge the vial prior to opening.
Usage
For Research Use Only! Not to be used in humans
Properties
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.
