2013
Here we describe a robust method for the fractionation of plant plasma membranes into detergent resistant and detergent soluble membranes based on a mixture of unlabeled and in vivo fully 15N labeled Arabidopsis thaliana cell cultures. The procedure is applied for comparative proteomic studies to understand signaling processes.

Fractional Distillation

Source: Laboratory of Dr. Nicholas Leadbeater — University of Connecticut Distillation is perhaps the most common laboratory technique employed by chemists for the purification of organic liquids. Compounds in a mixture with different boiling points separate into individual components when the mixture is carefully distilled. The two main types of distillation are "simple distillation" and "fractional distillation", and both are widely used in organic chemistry laboratories. Simple distillation...

In this protocol, we introduce a method for purifying the dendritic filopodia-rich fraction from the phagocytic cup-like protrusion structure on cultured hippocampal neurons by taking advantage of the specific and strong affinity between a dendritic filopodial adhesion molecule, TLCN, and an extracellular matrix molecule, vitronectin.
FAQs
A common denominator places fractions on the same unit scale. After equivalent fractions are formed, their numerators can be compared directly because each numerator counts the same-sized parts. The conversion changes the appearance of the fractions, not their quantities, so the resulting order remains valid.
Cross-multiplication compares two fractions without first writing a common denominator. For fractions a/b and c/d, multiplying a by d and c by b creates two products that reflect the same comparison. The larger product identifies the larger fraction, while equal products indicate equal values. This is efficient when denominators differ.
Decimal conversion expresses each fraction in a form that can be ordered by its numerical value. A number line provides a visual check: a fraction positioned farther to the right represents the greater quantity, while fractions at the same location are equal. These approaches offer alternatives when common denominators are less convenient.
A number line connects fraction comparison with the ordering of rational numbers. Fractions can be located according to their values, making relative position meaningful rather than relying only on symbolic calculations. The visual arrangement helps show whether one quantity is less than, greater than, or equal to another and reinforces the idea of equivalent locations.
First, identify a common denominator for the fractions. Next, rewrite each fraction in an equivalent form using that denominator, then compare the resulting numerators. Finally, translate the result into a less-than, greater-than, or equal-to statement. This sequence provides a systematic method while preserving the original fractional quantities.
Comparing Fractions supports decisions involving proportions, ratios, measurements, and probability. For example, it can establish which of two measured amounts is larger, determine whether one proportion exceeds another, or compare possible fractional outcomes. These applications make fraction ordering relevant to interpreting quantities and relationships across mathematics.
