1	VAPOR DIFFUSION, HANGING DROP	7	293	CRB2-BRCT2 (3.5MG/ML IN 0.05M TRIS-HCL PH7.0, 0.6M NACL, 5MM DTT) WAS MIXED WITH AN EQUAL VOLUME OF PEPTIDE (0.05M TRIS-HCL PH7.0, 0.1M NACL, 5MM DTT), TO GIVE A 1:30 MOLAR RATIO OF PROTEIN:PEPTIDE. CRB2-BRCT2/PEPTIDE (7MG/ML IN 0.05M TRIS-HCL PH7.0, 1M NACL, 5MM DTT) WERE CRYSTALLISED BY HANGING DROP VAPOUR DIFFUSION AT 20C. PLATECLUSTERS GREW FROM 2UL PROTEIN, 2UL WELL SOLUTION (0.1M NA-CACODYLATE PH6.5, 7.0% PEG8000 AND 0.2M CA-ACETATE) AND 0.5UL 0.1M PR(III) ACETATE.
