The solubility properties of granulopoiesis inhibiting factor

Experientia, 1975
The solubility of granulopoiesis inhibiting factor (GIF) in various aqueous and organic solvents was investigated. GIF is soluble in water, 10% acetic acid, and 10% pyridine. It is not extractable by 1-butanol at low and high pH. A high solubility was found in polar organic solvents (ethanol-acetone 9:1, and chloroform-methanol 1:1), whereas GIF seems ...

Entropic Factor in the Solubility of Small Particles

Journal of Pharmaceutical Sciences, 1971
A mechanistic basis for the dependence of solubility on particle size was investigated. The solubility difference between a crystalline and microcrystalline solid was determined; the microcrystalline solid had a greater solubility than the crystalline.

Soluble factors and the development of rod photoreceptors

Cellular and Molecular Life Sciences, 2000
Photoreceptors are the most abundant cell type in the vertebrate neural retina. Like the other retinal neurons and the Müller glia, they arise from a population of precursor cells that are multipotent and intrinsic to the retina. Approximately 10 years ago, several studies demonstrated that retinal precursor cells (RPCs) are competent to respond to ...

Soluble Receptors for Cytokines and Growth Factors

International Archives of Allergy and Immunology, 2009
Soluble cytokine and growth factor receptors are currently believed to play an important role in the regulation of biological activities of their ligands. In this review, the current ideas on the mechanisms and regulation of generation of soluble receptors and their possible physiological functions are presented.

Soluble factors involved in glioma invasion

Acta Neurochirurgica, 2003
Recent studies using molecular and cellular techniques of the factors regulating the invasion process have revealed a crucial role for a number of growth factors and cytokines. Their function lies on the one hand in the autocrine stimulation of the tumor cells themselves, resulting in the stimulation of protease expression and an enhancement of ...

A SOLUBLE CYTOTOXIC FACTOR FROM MACROPHAGES

Australian Journal of Experimental Biology and Medical Science, 1980
SummaryUnstimulated mouse peritoneal macrophages can lyse certain tumour cell lines via the action of a labile exotoxin, some of the properties of which are examined.

Soluble factors and solid phases

Current Biology, 1992
Macromolecules are constantly being transported between nucleus and cytoplasm in a selective, signal- dependent manner. This dynamic flux consists of the unidirectional transport of certain proteins and RNA molecules, and the bidirectional transport or ‘shuttling’ of other proteins and ribonucleoprotein particles.

Assay of Soluble Tumor Necrosis Factor Receptors

2003
Over the last decade, numerous basic biological as well as experimental and clinical studies have firmly established the significance of tumor necrosis factor (TNF) as a principal proximal mediator of sepsis (1-4). One of the major insights that has emerged during recent years has been that under physiological circumstances, TNF activity is tightly ...

Cytokines — soluble factors in immune responses

Current Opinion in Immunology, 1988
In the past a great deal of research in immunology was based on the premise that antigens were solely responsible for intracellular events leading to proliferation and differentiation, and that cell contact, antigen receptor ideotypic network, suppressor T cells and antigen specific helper and suppressor factors were the regulators of the immune ...
