| What does the color of my protein solution mean? Hi, maybe a cofactor like pyridoxal phosphate. Had a yellow protein with that as well...

| What does the color of my protein solution mean? A "blue" protein most likely contains a metal cofactor (i.e. iron) coordinated to Tyr and possibly Asp or Glu and Cys. Carlo On 10/30/06, Pow Joshi <[Only registered users see links. ]> wrote: |

| What does the color of my protein solution mean? Google quickly answers your question with at least one example: ceruloplasmin (color comes from Cu binding). I would bet more proteins (involved in Fe transport?) are out there. On 10/30/06, Pow Joshi <[Only registered users see links. ]> wrote: |
