产品说明(Description)
Recombinant Human Transforming Growth Factor beta 1 is produced by our Mammalian expression system and the target gene encoding Ala279-Ser390 is expressed.
Lyophilized from a 0.2 μm filtered solution of 50mM Glycine-HCl, 150mMNacl, pH2.5.
质量控制(Quality Control)
Purity: Greater than 95% as determined by reducing SDS-PAGE.
Endotoxin: Less than 0.01 EU/ug as determined by LAL test.
Bioactivity:
Measured by its ability to inhibit the IL-4-dependent proliferation of TF‑1 human erythroleukemic cells. The ED50 for this effect is 4-40 pg/ml.
复溶(Reconstitution)
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 distilled water Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
