The protocols for plastic and wax sections as used by the Vize lab. These protocols work, but they have not been optimized. If anyone has better protocols please let us know.Samples.Stain samples strongly, remember that in a section only the very strongest stain will be visible, even quite strong background will not be visible. BCIP/NBT is the only stain we have successfully used, we have tried Red new fuschin but it......阅读全文
