I have to CAM assay for some samples. I'm planning to conduct the assay in eggs only, but is it better to conduct it in petriplates? While adding drugs (on eggs), whether we should inject it to the veins after removing the albumin or to the yolk sac or is it just enough to add simply over the surface? Which is better to use for drug addition syringe or micropipette? How can do the image analysis of this assay? While we did for the first time we faced difficulties to take images of the CAM using mobile phones. Need a detailed working protocol for this CAM assay.
