Inhibition of CD22 (unknown origin) in human Daudi cells assessed as relative inhibitory potency in presence of biotinylated dimeric 2-(78-biotinoylamino-1,4,7,10,13,16-hexaoxa-octadecyl)-1,4-bis(2-aza-l-oxo-8-(sodium(5-acetamido-3,5,9-trideoxy-9-(4-phenylbenzamido)-D-glycero-a-D-galacto-non-2-ulopyranosyloxyonate))-5-thia-octyl) benzene preincubated for 15 mins followed by probe addition incubated for 20 mins by flow cytometric analysis relative to 1,4-Bis-(2-aza-1-oxo-8-(sodium-(5-acetamido-3,5-dideoxy-D-glycero-alpha-D-galacto-non-2-ulopyranosyloxyonate))-5-thia-octyl)benzene
