A rapid and sensitive method for the analysis of plasma free fatty acids with glass capillary column gas-liquid chromatography and flame ionization detection is described. The plasma sample, together with n-pentadecanoic acid as an internal standard, was treated with 2,2-dimethoxypropane

Immobilization of active urokinase on albumin microspheres: use of a chemical dehydrant and process monitoring.

K Bhargava et al.

Pharmaceutical research, 9(6), 776-781 (1992-06-01)

A method of immobilizing urokinase on albumin microspheres has been developed. Laser scattering, which was used to follow particle size from the initial emulsification stage to the final aqueous resuspension of the microsphere stage, showed that particle coalescence and crosslinking

Improved methods are described for anatomical investigation of small insects and other arthropods using serial semithin sections. The specimens were dehydrated with acidified 2,2-dimethoxypropane and embedded in ERL 4206 epoxy resin under vacuum. This procedure ensures good resin impregnation of

Acetonation of L-pentoses and 6-deoxy-L-hexoses under kinetic control using heterogeneous acid catalysts.

The fibrous polymer-supported sulfonic acid catalyst Smopex-101 H+ proved to be an efficient catalyst for the preparation of O-isopropylidene derivatives from a series of rare sugars. Acetonation of the reducing sugars L-arabinose, L-ribose, L-xylose, L-fucose, and L-rhamnose in N,N-dimethylformamide by

Improvements in dehydration and cement line staining for methacrylate embedded human bone biopsies.

H E Gruber et al.

Stain technology, 60(6), 337-344 (1985-11-01)

Undemineralized methacrylate embedded bone biopsies and other bone specimens can be processed much more rapidly by application of acidified 2,2-dimethoxypropane (DMP) dehydration, which requires two hours, than by traditional graded ethanol dehydration, which requires at least four days. This shortened

Preparation and synthetic application of partially protected brassinosteroids.

Vladimir A Khripach et al.

Steroids, 75(1), 27-33 (2009-09-30)

Preparation of partially protected brassinosteroids is achieved through the reaction of the source material (24-epicastasterone and 24-epibrassinolide) with diol-specific reagents (2,2-dimethoxypropane and methylboronic acid). The obtained products were shown to be useful synthetic intermediates for further preparation of minor representatives

Preparing living pollen material for scanning electron microscopy using 2,2-dimethoxypropane (DMP) and critical-point drying.

Biotechnic & histochemistry : official publication of the Biological Stain Commission, 73(3), 137-143 (1998-07-23)

A simple, quick, and inexpensive method for preparing any type of pollen material is described. Fresh, mature pollen grains without previous chemical fixation are dehydrated in acidified 2, 2-dimethoxypropane (DMP) followed by critical-point drying in CO2. This method helps preserve

Determination of individual human faecal bile acids by gas-liquid chromatography after enzymatic deconjugation and simultaneous solvolysis and methylation using dimethoxypropane.

Chemical dehydration of specimens with 2,2-dimethoxypropane (DMP) for paraffin processing of animal tissues: practical and economic advantages over dehydration in ethanol.

K Conway et al.

Biotechnic & histochemistry : official publication of the Biological Stain Commission, 74(1), 20-26 (1999-04-06)

Chemical dehydration can be accomplished using 2,2-dimethoxypropane (DMP). In the presence of an acid catalyst, this liquid reacts with water generating methanol and acetone as products. Although DMP is more expensive per milliliter than ethanol and other solvents used for

Delivery of therapeutic protein for prevention of neurodegenerative changes: comparison of different CSF-delivery methods.

Neil R Marshall et al.

Experimental neurology, 263, 79-90 (2014-09-24)

Injection of lysosomal enzyme into cisternal or ventricular cerebrospinal fluid (CSF) has been carried out in 11 lysosomal storage disorder models, with each study demonstrating reductions in primary substrate and secondary neuropathological changes, and several reports of improved neurological function.

Matrix isolation infrared and ab initio study of the conformations of 2,2-dimethoxypropane.

V Venkatesan et al.

Spectrochimica acta. Part A, Molecular and biomolecular spectroscopy, 59(7), 1497-1507 (2003-04-26)

Conformations of 2,2-dimethoxypropane (DMP) were studied using matrix isolation infrared spectroscopy. An effusive source maintained at different temperatures (298, 388 and 430 K) was used to deposit DMP in a nitrogen matrix. As a result of these experiments, spectrally resolved

Problems of the use of 2,2-dimethoxypropane as dehydrating agent in preparing single cells for transmission electron microscopy.
