Hi,
1. Yes, wash the extra CD3. check the regular protocol for CD3 plate coating.
see my previous answer:"Because anti-CD3 will cause cell death, that's why anti-CD3 is plate-bound and we transfer culture to new plate."
check the protocol step 5" Transfer the culture to new plate after 2 days without digesting or changing the medium."
