Beta-Galactosidase/lacZ Staining

[Jesus Torres]

Hi,

	I am looking for protocols to stain larval imaginal discs 
expressing nuclear Beta-Galactosidase (lacZ) reporter, either by 
antibody staining or by activity staining.

	I have done this in the past using reporters which were 
strong expressors, however I have some transgenes that drive weak 
expression, and I have not been able to visualize them succesfully.

	If you have any protocol for this, I would really appreciate 
if you share it with me, specially if you have any suggestions about 
particular reagents, fixatives or buffers that seem to be critical in 
your hands.

	I appreciate your help.

	Best,
