 Twenty-Four Plate Manual Replicator Transfers:  

Transferred to 200 ul 50 mM Tris, pH 8.0 in Assay Plate 1A

Pins washed in ~150 ml dH2O, blotted

Pins washed in ~150 ml Isopropanol, blotted, dried.

Pins transferred to 200 ul 50 mM Tris, pH 8.0 in Assay Plate 1B

Pins washed in fresh dH2O and Isopropanol, dried.

 

2.         Pins dipped into 200 ul FITC in 100% DMSO in Source Plate

Transferred to 200 ul 50 mM Tris, pH 8.0 in Assay Plate 2A

Pins washed in ~150 ml dH2O, blotted

Pins washed in ~150 ml Isopropanol, blotted, dried.

Pins transferred to 200 ul 50 mM Tris, pH 8.0 in Assay Plate 2B
