Product Description |
Recombinant Human FGF8b-Protein is expressed from E.coli without tag.It contains Gln23-Arg215. |
Product Background |
Two of the four human FGF8 splice isoforms, FGF8a and FGF8b, are expressed in the mid-hindbrain region during development. Although the only difference between these isoforms is the presence of an additional 11 amino acids at the N terminus of FGF8b, these isoforms possess remarkably different abilities to pattern the midbrain and anterior hindbrain. |
