To understand how memories are formed and maintained, neuroscientists travel far beyond the cell body in search of answers.
Brain cell in purple on a black background. Arc mRNAs are labeled green and are mainly localized in the cell nucleus and in the dendrites.

A gene essential for information storage in the brain engages an autoregulatory feedback loop to consolidate memory.
Neurons (green) fire differently depending on whether the astrocytes (red) they are grown with are cultivated from people with or without fragile X.

Stratagene's Vitality™ hrGFP (green fluorescent protein) mammalian expression vectors allow protein expression and subcellular localization studies similar to those using jellyfish (Aequorea victoria) GFP, with one important difference: Stratagene's hrGFP exhibits less toxicity in many mammalian cells. Renilla reniformis, an Anthazoan sea pansy related to the jellyfish, produces a 238 amino-acid protein that has broader pH stability, more resistance to solvents, detergents, and proteases,
Scientists Use Various Methods To Tackle Protein Purification
James Kling | Jul 6, 1997 | 8 min read
Tedious, time-consuming, exasperating: Those are perhaps the three words that researchers use most commonly to describe protein purification. Proteins, and their little sisters the peptides, are among the most difficult compounds to purify. Enzyme degradation and chemical decomposition conspire to ruin protein samples throughout the steps of purification. Proteases in the original sample and varying salt concentrations can result in degradation or precipitation. Varying pH and temperature may

Gel Microdrop System from One Cell Systems can ferret out rare protein secreting cells Imagine, if you will, a single cell suspended in a drop. Now picture that same cell secreting a protein, say an immunoglobulin. Now envision that secreting cell embedded in a matrix that binds the protein as it leaves the cell, and you have the idea of the microdrop hybridoma selection system available from One Cell Systems. A modification of the microdrop technology described in 1991 by James Weaver, Associ
