Question 1: Does Cytoskeleton sell lysis buffer for activation assays?
Answer 1: Unfortunately Cytoskeleton does not sell lysis buffer for the activation assays. The lysis buffers differ by kit which is why we include the uniquely-formulated and tested buffer with each activation assay.
Question 2: Which is the most stable/brightest Acti-stain conjugate?
Answer 2: The brightest and most stable of the Acti-stains is Acti-stain 488 (green fluorescence; Cat. # PHDG1). Please see the table below for additional information on all of our Acti-stains.
