To Gel or Not To Gel?

SPE Annual Technical Conference and Exhibition, 2009
Abstract Since its commercialization in 1949, hydraulic stimulation has been used on thousands of wells worldwide to increase hydrocarbon production. There are some areas where hydrocarbon production would not be economically viable without this process.

To gel or not to gel

Blood, 2011
In this issue of Blood , Chernysh et al examine the pregelation phase of fibrin polymerization, and by demonstrating heterogeneous polymeric structures that progressively coalesce into scaffolds provide novel insights into this process with potential implications on circulating soluble fibrin.[1 ...

Bécaplermine gel (Regranex® gel)

Annales de Dermatologie et de Vénéréologie, 2004
Becaplermine gel (Regranex) is an hydrogel which contains 100 microg of Platelet Derived Growth Factor-BB (rhPDGF-BB) per gram. Regranex is presented in 15-gram multidose tubes. It has been approved as adjuvant treatment for neuropathic diabetic ulcerations of less than 5 cm2, extending into the subcutaneous tIssue, in the absence of ischemia, in ...

Gel matrices for scanning gel chromatography

Biophysical Chemistry, 1979
I have examined the light-scattering behavior of a number of gel matrices used in gel filtration chromatography. The angular dependence of light scattering by Sephadexes is consistent with treatment of the particles as large scattering particles with a low refractive index increment (mu).

Thrombocytolysis in Gel

International Archives of Allergy and Applied Immunology, 2009
Cytolysis test in agarose gel was applied to study surface antigens of platelets. By means of rabbit antisera to nucleated cells and/or erythrocytes, species-specific antigens were demonstrated on platelets of various species. In studying reactions of human platelets with rabbit antisera, it was found that species antigens shared by nucleated cells and

Chitin gels

International Journal of Biological Macromolecules, 1989
Chitin dissolved in N,N-dimethylacetamide, N-methyl-2-pyrrolidone and their mixed solvents in the presence of 5% LiCl was treated with acetic anhydride-pyridine, and the mixture solution was heated at 100 degrees C for 6 h to give a partially O-acetylated chitin gel. Chitin dissolved in these solvents in the presence of 5% LiCl was mixed with pyridine,

Immunodiffusion in Gels

2003
Immunodiffusion in gels encompasses a variety of techniques that are useful for the analysis of antigens and antibodies (1). The fundamental immunochemical principles behind their use are exactly the same as those that apply to antigen#x2013;antibody interactions in the liquid state.
