All compounds have been analyzed by thin layer chromatography (TLC) and 1H NMR and/or mass spectrometry for purity. For non-biotinylated compounds, the purity may vary between samples but should at least be 90+%. Impurities may include traces of
spacer derivative, Sug-b-CH2CH2N3, and or traces of salt or other unidentified
organic material. Biotinylated compounds are estimated to have an purity of 95+%. Aliquots of the compounds
were in water and were lyophilized. The accuracy of the weight was estimated to
