High impact information on Aminopropylsilane

  • Human erythrocytes were attached to cover slips (glass or mica) treated with aminopropylsilane and glutaraldehyde, and then disrupted by direct application of a jet of buffer, which removed the distal portion of the cells, thus exposing the cytoplasmic surface (PS) of the flattened membranes [1].
  • To maintain a constant and adequate buffer flow toward the CE capillary outlet for stable CE and ESI operation, low pressure was applied to the inlet of the CE when an untreated or degraded APS capillary was used [2].
  • In a comparison using capillaries ranging from either 100 to 10 microns or 50 to 5 microns ID and chemically modified with aminopropylsilane, a 25- to 50-fold increase in sensitivity was observed for both peptide and protein mixtures [3].
  • Using a quadrupole mass spectrometer, an aminopropylsilane-coated capillary, and a wide scan mass-to-charge ratio range of 500-1400, detection limits of approximately 4, 1, and 0.6 fmol for cytochrome c and myoglobin were achieved for 75-, 50-, and 30-micron inner diameter capillaries, respectively [4].
  • The adsorption kinetics of purified fibrinogen to unmodified and aminopropylsilane-modified quartz glass surfaces were studied under pseudo-first order (binding-unit excess) conditions by the total internal reflection fluorescence (TIRF) method [5].

Associations of Aminopropylsilane with other chemical compounds

  • Five different materials with surface wettability ranging from hydrophilic (underwater contact angle 25 degrees) to hydrophobic (underwater contact angle 111 degrees) were used, i.e., clean glass (GLASS), aminopropylsilane (APS), octadecylsilane (ODS), polylactate (PL), and silicone (SI) [6].
  • METHODS: Live bacterial cells were deposited on to aminopropylsilane treated glass coverslips by centrifugation, dried, then reacted with either 1% (w:v) n,n,n',n'-tetramethyl-p-phenylene diamine (TPD) or 5 mM diaminobenzidine (DAB) at 37 degrees C. The preparations were mounted in 50% glycerol and assessed by brightfield microscopy [7].
