Can anyone help me with these chemicals?

I need to know what the excitation and emission wavelengths are. I think
the Calcein is probably Calcein Green so I know that one but I am not 100%
sure of that. They have been used on some bone samples that someone has
brought to me in the hope that we can visualise them with the Confocal. I
can see the Calcein in the 510nm range but am not sure what I am getting in
the second channel of my microscope it could be a combination of bith the
Xylenol orange or the tetracycline???

The samples have all been prepared some time ago so I don't think we can do
anything about the preparation.

  tetracycline hydrochloride (Supramycina
pro infusione 500mg,
  5mg/kg calcein (Calcein C-0875, Sigma Chemical
xylenol orange
(Xylenol Orange X-0127,

CALCEIN IS BLUE OR GREEN, TETRACYCLINE-YELLOW,
 >XYLENOL-ORANGE.

I would very much appreciate any ideas

Thanks
