The MaxDiscovery™ Human GM-CSF ELISA Test Kit is designed for quantitative determination of the concentration of human GM-CSF in serum, plasma, and cell culture supernatant. Human granulocyte/monocyte-colony stimulating factor (GM-CSF) is a 14 kDa protein composed of 127 amino acids. It was initially characterized as a growth factor that can support the in vitro colony formation of granulocyte-macrophage progenitors. It is differentially glycosylated factor produced mainly by activated T cells and macrophages. Endothelial cells and fibroblasts can also produce GM-CSF after exposure to TNF-a, IL-1, IL-2 and IFN-?. GM-CSF is found associated with extracellular matrix and in membrane-bound formats too. GM-CSF stimulates proliferation, activation and differentiation of macrophages and granulocytes and their progenitors.
Retractable Protein Nanoneedles The ability to control the transfer of molecules through cellular membranes is an important function in synthetic biology; a new study from researchers at Harvard’s Wyss Institute for Biologically Inspired Engineering and Harvard Medical School (HMS) introduces a novel mechanical method for controlling release of molecules inside cells.A Crystal Clear View of Biomolecules Fundamental discovery triggers paradigm shift in crystallography.Charting Kidney Cancer Metabolism Changes in cell metabolism are increasingly recognized as an important way tumors develop and progress, yet these changes are hard to measure and interpret. A new tool designed by MSK scientists allows users to identify metabolic changes in kidney cancer tumors that may one day be targets for therapy."Dark Side" of the Transcriptome New approach to quantifying gene "read-outs" reveals important variations in protein synthesis and has implications for understanding neurodegenerative diseases.Advancing Synthetic Biology Living systems rely on a dizzying variety of chemical reactions essential to development and survival. Most of these involve a specialized class of protein molecules — the enzymes.Structure of Brain Plaques in Huntington's Researchers at the University of Pittsburgh School of Medicine have shown that the core of the protein clumps found in the brains of people with Huntington's disease have a distinctive structure, a finding that could shed light on the molecular mechanisms underlying the neurodegenerative disorder. Visualizing a Cancer Drug Target at Atomic Resolution Using cryo-electron microscopy, researchers were able to view, in atomic detail, the binding of a potential small molecule drug to a key protein in cancer cells.Pumpjack" Mechanism for Splitting and Copying DNA High-resolution structural details of cells' DNA-replicating proteins offer new insight into how these molecular machines functionThe Power of Three Overlooked portion of cell “death receptor” critical in some cancers, autoimmune diseases.Biomarker for Recurring HPV-Linked Oropharyngeal Cancers A look-back analysis of HPV infection antibodies in patients treated for oropharyngeal (mouth and throat) cancers linked to HPV infection suggests at least one of the antibodies could be useful in identifying those at risk for a recurrence of the cancer, say scientists at the Johns Hopkins University.
