In attempting to improve specificity of staining , the fluorescein labeled antisera used in both direct and indirect methods were treated in one of several ways : ( 1 ) They were passed_through Dowex-2-chloride twice and treated with acetone insoluble powders ( Coons , 1958 ) prepared from mouse liver or from healthy sweet_clover stems or crown_gall tissue produced by Agrobacterium_tumefaciens ( E._F._Smith + Townsend ) Conn , on sweet_clover stems .

However , the nonspecific staining by the * * f in tumor sections was considered bright enough to be confused with the staining of small amounts of WTV antigen .

However , the nonspecific staining by the * * f in tumor sections was considered bright enough to be confused with the staining of small amounts of WTV antigen .

Two absorptions of * * f with ethyl_acetate or two absorptions of * * f ( which had been passed_through Dowex-2-chloride ) , NS and * * f with crown_gall tissue powder , or mouse liver powder did not further improve the specificity of staining .

Rinsing the sections with PBS before layering the intermediate sera did not improve the staining reaction .

Frequently a_few isolated thick walled cells or , rarely , groups of such cells in the xylem region , were also specifically stained , but there was no such staining in epidermis , cortex , most xylem cells , ray cells , or pith .

In both the direct and indirect methods of staining , the conjugates had nonspecifically staining fractions .

After * * f and * * f were passed_through Dowex-2-chloride twice and treated twice with healthy sweet_clover tissue powder , nonspecific staining was greatly reduced but a disturbing amount of such staining was still present .

After * * f and * * f were passed_through Dowex-2-chloride twice and treated twice with healthy sweet_clover tissue powder , nonspecific staining was greatly reduced but a disturbing amount of such staining was still present .

Treatment of the conjugates with ethyl_acetate , and the conjugates ( which had been passed_through Dowex-2-chloride ) with mouse liver powder , sweet_clover crown_gall tissue powder , or healthy sweet_clover proteins did not satisfactorily remove nonspecifically staining substances in the conjugates .
