Ribosomes associated with the heavy membranefraction were removed after treatment. However, tubulin associated with the heavy membranefraction dissociated from the membrane at metaphase. Further, a-tubulin was found in abundance only in the light membranefraction, and was reduced or absent, respectively, in the intermediate and heavy membrane fractions. However, in our study the relative levels of tubulin present in any membranefraction showed no decrease during maturation and activation. However, when it was compared with samples containing the same membranefraction from different females we observed that a few protein bands were often variable in staining intensity. This is corroborated by the fact that a high proportion of extrinsic proteins were present in the light membranefraction in comparison with the other fractions. Various electron transport activities were analysed in the mitochondrial membranefraction of the filarial worm. The possibility that monomeric tubulin sedimented with the membrane fractions as a contaminant may be ruled out since tubulin was not associated with the heavy membranefraction of mature oocytes. The (a) light, (b) intermediate and (c) heavy membrane fractions isolated from activated eggs are shown, as well as (d) the heavy membranefraction isolated from mature oocytes. Peripheral and integral membrane fractions can be extracted from the remaining membranefraction. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Sometimes a particular membranefraction can be isolated first, such as isolating mitochondria from cells before purifying a protein located in a mitochondrial membrane.

Occasionally c-mos protein was detected in the light membrane fractions derived from both mature oocytes and activated eggs. Aminopeptidase-like activity was present in membrane fractions from all species and stages examined. In addition, biochemical soluble and membrane fractions were prepared from immature and mature brains. From top to bottom: the light, intermediate, and heavy membrane fractions. The evidence that the tubulin found was not from microtubules which co-precipitated with isolated membrane fractions is as follows. Tubulin remained associated with light and intermediate membrane fractions at all the stages of meiosis examined. These examples are from corpora and from sources on the web.
