Distinct forebrain and cerebellar isozymes of type II Ca^(2+)/calmodulin-dependent protein kinase associate differently with the postsynaptic density fraction [PDF]
, 1985 Forebrain and cerebellar Type II Ca2+/calmodulin-dependent protein kinases have different subunit compositions. The forebrain holoenzyme, characterized in our laboratory, is a 650-kDa holoenzyme composed of 50-kDa alpha-subunits and 60-kDa beta-subunits ...

From colloidal dispersions to colloidal pastesthrough solid–liquid separation processes [PDF]
, 2005 Solid–liquid separation is an operation that starts with a dispersion of solid particles in a liquid and removes some of the liquid from the particles, producing a concentrated solid paste and a clean liquid phase.

Density Gradient Centrifugation Studies of Rubella Virus
Experimental Biology and Medicine, 1966 SummaryRubella virus was grown in three different mammalian kidney cell lines. The resulting virus-containing supernates were concentrated by forced dialysis and were then studied for density on sucrose gradients. All of the virus preparations produced peaked infectivity bands with 99% of the infec-tivity concentrated in a band from 1.040 to 1.120 g ...

Deletion mutants of bacteriophage phiX174 [PDF]
, 1972 Mutants of bacteriophage phiX174 have been isolated that are less dense than wild-type phiX particles in CsCl. When mutant viral (+) strand DNA and wild-type complementary (-) strand DNA are hybridized, the resulting duplex molecules have single-stranded

Biosynthetic pathway of mitochondrial ATPase subunit 9 in Neurospora crassa [PDF]
, 1983 Subunit 9 of mitochondrial ATPase (Su9) is synthesized in reticulocyte lysates programmed with Neurospora poly A-RNA, and in a Neurospora cell free system as a precursor with a higher apparent molecular weight than the mature protein (Mr 16,400 vs.

Abridged Ribosome Profiling for Accurate Bacterial Translation Measurements
Methods and ProtocolsRibosome profiling, or Ribo-Seq, is a powerful tool for studying translation. It maps the positions of translating ribosomes on mRNAs, providing insights into actively expressed genes. Unlike mass spectrometry, Ribo-Seq is not affected by the same biases

Nature of {varphi}X174 Linear DNA from a DNA Ligase-Defective Host [PDF]
, 1974 Linear DNAs have been prepared from {varphi}X phage and from {varphi}X RF II (double-stranded circular form of {varphi}X DNA, formed during infection and nicked in one or both strands) molecules derived from infection at the restrictive temperature of ...
