Which caspase-3 antibody do you recommend for use in IF assays on human cells or frozen tissue?

For imaging purposes, we recommend using Cleaved Caspase-3 (Asp175) Antibody #9661 or Cleaved Caspase-3 (Asp175) (D3E9) Rabbit mAb #9579 on human cells and frozen tissues.  We have noted cytoplasmic background with Cleaved Caspase-3 (Asp175) (5A1E) Rabbit mAb #9664 in some human samples.
