This scFv was therefore used as control in experiments where another anti - Ras scFv ( Y259 scFv , derived from the neutralizing anti - Ras mAb Y13 - 259 ) blocked the Ras pathway in vitro and led to tumor regression in a nude mouse model [ Cochet , O . , Kenigsberg , M . , Delumeau , I . , Virone - Oddos , A . , Multon , M .
