Synthesis and biochemical characterization of EGF receptor in a water soluble membrane model system

PMCID: 5460842
PMID: 28586369
DOI: 10.1371/journal.pone.0177761

[…] nlps to the sensors. plots of association responses (nm) from 1990–1995 s were created against log concentration [m] of empty or egfr-nlps and ec50 and hill slopes were calculated using a sigmoidal dose response fitting with variable slope in graphpad prism. to determine the inhibition of egfr-nlp to egf binding, 100 nm egfr-nlps were incubated with 1 μm unlabeled egf or a 1.5-fold titration […]


Identification and Characterization of the Interaction Site between cFLIPL and Calmodulin

PMCID: 4631386
PMID: 26529318
DOI: 10.1371/journal.pone.0141692

[…] all experiments were conducted in triplicate. kd and ic50 values were obtained through data fitting performed in kaleidagraph using a four-parameter logistic model, according to the sigmoidal dose-response fitting function: y=m1+(m2-m1)1+(xm3)m4(1) where m1 and m2 are the fluorescence intensity values at zero and maximum analyte concentrations, respectively, x is the analyte […]


Cell cycle association and hypoxia regulation of excision repair cross complementation group 1 protein (ERCC1) in tumor cells of head and neck cancer

PMCID: 4158184
PMID: 24817012
DOI: 10.1007/s13277-014-2001-2

[…] the treated cells were related to the controls as percentage of growth capacity. the relationship between growth capacity and treatment drug concentrations was analyzed by regression using nonlinear dose-response fitting methods of graphpad prism 4.03 (graphpad software inc, san diego, ca, usa), and concentrations were determined, which cause 50 % growth inhibition compared to untreated cells […]


In This Issue of Diabetes Care

PMCID: 3781500
DOI: 10.2337/dc13-ti10

[…] cross-sectional association between severity of dr and cognitive impairment. while only 5% of the pdr group had results indicating severe cognitive impairment or dementia, 12% of those with no/mild dr fit this description. the authors point out that a number of factors should be considered when interpreting their results. these include the possibility that residual confounding associated […]


Rapid on site/in situ detection of heavy metal ions in environmental water using a structure switching DNA optical biosensor

PMCID: 3725506
PMID: 23892693
DOI: 10.1038/srep02308

[…] with the dose-response curve and the s/n ratio of 5.1, the detection limit was determined as approximately 1.2 nm based on the average standard deviation of the measurements (σ) and the slope of the dose-response fitting curve (s) as 3σ/s. therefore, this novel sensor can be applied to the direct detection of hg2+ in natural water with the ability to meet even the most stringent requirements […]


Inhibition of poly(ADP ribose) Polymerase Interferes with Trypanosoma cruzi Infection and Proliferation of the Parasite

PMCID: 3457943
PMID: 23049934
DOI: 10.1371/journal.pone.0046063

[…] but the incubation time was set so that the substrate conversion in the control wells was approximately 20%. the fluorescence signal was converted to inhibition percentage and fitted using sigmoidal dose-response fitting with variable slope (graphpad prism). the curves were extrapolated to 0% and 100% of inhibition by setting their inhibitor concentration 2 log units below or above the first […]
