The Good
Comes directly labelled with FITC and relatively cheap. Although not shown here, likely works well against mouse tissues.
The Bad
Does not recognize human CD3
The Bottom Line
If you are in an immediate need of an antibody against human CD3 and the only one you have on hand is this product, do not bother as it does not recognize human CD3. It is best to find a validated anti-CD3 antibody for human tissue (which should be no problem given the several that are commercially available).
