Recombinant Human Interleukin-21 is produced by our E.coli expression system and the target gene encoding Gln23-Ser155 is expressed.
Less than 0.1 ng/µg (1 IEU/µg) as determined by LAL test.
Estimated molecular weight
Lyophilized from a 0.2 µm filtered solution of 20mM PB,150mM NaCl,pH7.2.
Greater than 95% as determined by reducing SDS-PAGE.
Always centrifuge tubes before opening. Do not mix by vortex or pipetting.It is not recommended to reconstitute to a concentration less than 100 µg/ml.Dissolve the lyophilized protein in ddH2O.Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
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.
