Nodal, also known as Nodal homolog, is a secreted protein member of the Transforming Growth Factor-beta (TGF-beta) superfamily. It is essential for the formation of mesoderm and axial patterning during early vertebrate embryonic development.
Formulation- Lyophilized from a 0.2 µm filtered solution in Acetonitrile and TFA (with BSA as a carrier protein)
Endotoxin Level- <1.0 EU/µg of recombinant protein as determined by the LAL method.
Storage Condition- The lyophilized protein is stable for at least one year from date of receipt at -70°C. Upon reconstitution, this cytokine can be stored in working aliquots at +2° to +8°C for one month, or at -20°C for six months, with a carrier protein without detectable loss of activity.
Avoid repeated freeze/thaw cycles.
