The age structure of populations of Saccharomyces cerevisiae
(Elsevier, 1981-04)
A discrete deterministic model is described for the growth of an age-structured population of yeast, Saccharomyces cerevisiae, incorporating recent information on the asymmetry of cell division and control of the cell cycle ...
Protein release from Escherichia coli cells permeabilized with guanidine–HCl and Triton X100
(Wiley Subscription Services, Inc., A Wiley Company, 1989-02-20)
An important factor complicating the recovery of recombinant proteins from Escherichia coli is their intracellular location. An alternative to the commonly used method of releasing these proteins by mechanical disruption ...
Substrate-dependent differences in production of extracellular matrix molecules by squamous carcinoma cells and diploid fibroblasts
(Wiley Subscription Services, Inc., A Wiley Company, 1989-04-20)
Two human squamous carcinoma cell lines and human diploid fibroblasts were examined for the production of extracellular matrix (ECM) molecules including fibronectin (FN), laminin (LN), and thrombospondin (TSP) when grown ...
A molecular model for singlet/singlet energy transfer of monovalent ligand/receptor interactions
(Wiley Subscription Services, Inc., A Wiley Company, 1991-05)
A stochastic model is described that predicts the degree of singlet/singlet energy transfer in complexes formed between monovalent ligands and monovalent receptors. The modeling approach is intended to serve as an analytical ...
An initial-value method for the solution of certain nonlinear diffusion equations in biology
(Elsevier, 1970)
The steady-state one-dimensional diffusion equation with a nonlinear source term is a class of differential equations governing the behavior of many biological systems. As with other types of nonlinear differential equations, ...
Effects of phosphate, glucose, and ammonium on cell growth and lincomycin production by Streptomyces lincolnensis in chemically defined media
(Wiley Subscription Services, Inc., A Wiley Company, 1985-03)
Cell growth and lincomycin production were measured in batch cultures of Streptomyces lincolnensis in chemically defined media. In these fermentations the specific rate of antibiotic production was maximal during growth ...
Growth of three established cell lines on glass microcarriers
(Wiley Subscription Services, Inc., A Wiley Company, 1983-05)
Three established cell lines were examined for growth on a newly developed microcarrier which consists of glass beads. The cells were simultaneously exmined for growth on commercially available microcarriers made from ...
Post-thaw suspension of red cells cryopreserved with hydroxyethyl starch
(Elsevier, 1978-08)
Post-thaw suspension of red cells cryopreserved with hydroxyethyl starch (HES) gives rise to an increase in the quantity of supernatant hemoglobin and a reduction in cell recovery. This occurs regardless of the suspension ...
Red cells preserved with 10% hydroxyethyl starch: Effect of prefreeze washing
(Elsevier, 1975-10)
Prefreeze washing of red cells with saline and other wash solutions before freezing with 10% hydroxyethyl starch does not yield an improved product after thawing. The saline stabilities and cell recoveries are reduced and ...
The preservation of erythrocytes at liquid nitrogen temperatures with hydroxyethyl starch: the removal of hydroxyethyl starch from erythrocytes after thawing
(Elsevier, 1971-12)
Packed human erythrocytes were frozen in liquid nitrogen using hydroxyethyl starch as a cryoprotective agent. Upon thawing, the cells were washed with a balanced salt solution. The washed cells were stable when resuspended ...
