Dr Fit citations


Synergistic antifungal effect of chitosan stabilized selenium nanoparticles synthesized by pulsed laser ablation in liquids against Candida albicans biofilms

PMCID: 5937483
PMID: 29760550
DOI: 10.2147/IJN.S151285

[…] The IC50 was calculated by dose–response fitting using Origin 9 software. The graphs show the mean ± standard error of the mean from three separate experiments performed in duplicate. For quantitative assays, statistical analys […]


Neonicotinoids act like endocrine disrupting chemicals in newly emerged bees and winter bees

Sci Rep
PMCID: 5591280
PMID: 28887455
DOI: 10.1038/s41598-017-10489-6

[…] For acute toxicity studies, the LD50 values were calculated using the Dr. Fit program (within R stats program) that uses a modified model and automated fitting procedure to describe dose-response curves with monotonic and multiphasic features. The resulting general mode […]


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

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

[…] f 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 ser […]

[…] L of kinase detection reagent was added. After incubation at room temperature for 30 minutes, the luminescence was recorded. The EC50 values were calculated using nonlinear regression with normalized dose–response fitting using Prism software (GraphPad Software, San Diego, CA, USA). To exclude the possibility that the increased kinase activity might be due to aggregation, 0.02% Triton-X was used a […]


The effects of arginine glutamate, a promising excipient for protein formulation, on cell viability: Comparisons with NaCl

PMCID: 4837223
PMID: 26873863
DOI: 10.1016/j.tiv.2016.02.002

[…] o software (Tree Star Inc., Ashland, OR, USA). Dose response curves were obtained and IC50 values (the concentration/osmolality required to cause a 50% loss in viability) calculated using the inbuilt dose–response fitting function with a nonlinear fit analysis in the OriginPro software version 9.0. […]


Activation of the Nrf2 ARE pathway by the Alternaria alternata mycotoxins altertoxin I and II

PMCID: 5225202
PMID: 27178040
DOI: 10.1007/s00204-016-1726-7

[…] of 24 h and WST-1 dye was added in serum-free medium. After 45 min the absorption at 450 nm was measured, values were normalized to respective control. The EC50 was calculated with OriginPro 9.1 with dose–response fitting. […]
