Fecal coliform recoveries were determined for six types of membrane filters using 65 nonchlorinated water samples. Results showed that the membranes could be ranked in order of decreasing recovery as follows: Millipore HC greater than Gelman greater than Johns-Manville approximately Sartorius greater than Millipore HA greater than Schleicher & Schuell.

A method for the titration of antigens based on separation by filtration through millipore filters of the complex of antigen with fluorescein isothiocyanate-labeled antibodies from free labeled anti­ bodies and nonspecific y-globulins is described. The fluorescence of the antigen-antibody complex is measured directly on the millipore filters using the Turner fluorometer equipped with a paper ch...

AIM We compared four commonly used, commercially available reverse phase nanoLC columns for identification/determination of Wnt/β-catenin-related pathway proteins. MATERIALS & METHODS The columns were: Chromolith® (silica monolith; Merke Millipore, MA, USA), PepMap™ (porous particles; Thermo Fisher Scientific, MA, USA), Accucore™ (solid core particles; Thermo Fisher Scientific) and PepSwift™ ...

Matrix-mediated epitheliomesenchymal interactions control dental cytodifferentiations. Experiments were performed in order to study the effects of noncollagenous proteins extracted from dentin on cultured enamel organs and dental papillae. Seven noncollagenous protein fractions were prepared from rabbit incisor dentin and used as substrates to coat Millipore filters. Embryonic mouse tooth germs...

The specificity of labeling enteroviruses with (32)P-labeled NaH(2)PO(4) or (14)C-leucine can be determined by comparing the percent adsorption of infective particles and radioactivity to membrane (Millipore) filters.

Homogeneous suspensions of streptomycete spores were desirable for plating after mutagenesis. Filtration through 8-mum membrane filters (Millipore Corp.) more effectively separated hyphae and spore clumps from single spores than did filtration through cotton wefts or paper.

The purpose of this study was to investigate the behavior of rat bone marrow cells (RBM) growing on surfaces with different pore sizes. RBM behavior on Millipore filters (MF-Millipore membrane filter) made from cellulose mixed esters with 5 different pore surfaces (0.45 microm, 1.2 microm, 3.0 microm, 5.0 microm and 8.0 microm) were compared in terms of morphological changes on the different po...
