A protein that controls proliferation, cellular differentiation, & other functions in most cells
Human 293 cell expressed
Purity by SDS-PAGE
Endotoxin Level< 1.0 EU per 1 ug of protein
ED₅₀ is typically 0.1 to 0.5 ng/mL. The specific activity was determined by the dose-dependent inhibition of IL-4 induced proliferation of mouse HT-2 cells (BALB/c spleen activated by sheep erythrocytes in the presence of IL-2).
0.1 to 0.5 ng/ml
25 kDa, homodimer, nonglycosylated
Physical form description
Lyophilized from 50 mM sodium acetate, pH 4.5 and 350 mM NaCl.
Reconstitute in sterile 4 mM HCl containing 0.1% endotoxin-free recombinant human serum albumin.
Centrifuge the vial prior to opening.
For Research Use Only! Not to be used in humans
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.
