Hi Gret Stuart.
Preperation of stock solution:For prepering any concentration use only 10 percent methanol and phosphate buffer of 0.01M, pH 8.0.Disolve erythromycin base in methanol and then make up volume by buffer.
Also for prepering agar plates add, after autoclave in the srerilized medium, Erythromycin solution prepared in methanol
