英文摘要 | a new mesoporous silica material with modified external and internal surfaces (alkyl diol-vinyl-sio(2)) was prepared and applied to selectively extract low molecular weight (lmw) proteins and peptides (less than 11 kda) from biological samples. x-ray diffraction, n(2) adsorption, transmission electron microscopy, and fourier transform infrared spectroscopy were used to characterize the alkyl diol-vinyl-sio(2). this material was used to extract lmw proteins (peptides) from standard proteins, a mixture of peptides, and crude human plasma. we compared the amounts of different proteins adsorbed by alkyl diol-vinyl-sio(2) and by vinyl-sio(2) (vinyl group on the internal surface of the mesoporous silica material). the desorption recovery of alkyl diol-vinyl-sio(2) by different eluents was also investigated by using a standard protein (insulin) as a model lmw protein. the material could efficiently extract lmw proteins and peptides from a mixture of standard proteins and crude human plasma with good extraction efficiency and desorption recovery. furthermore, the alkyl diol-vinyl-sio(2) had much better extraction selectivity for lmw proteins and peptides than a commercial c(18) solid phase extraction material. |
