Oestrogen and PR status was determined through the ligand-binding assay from 1990 to 2005 and then by immunohistochemistry (IHC).
In parallel comparisons from the same data obtained from the binding assays, the Scatchard plot, the Woolf plot and the saturation radioligand-binding curve gave similar estimates of the K d (7.81, 7.935 and 8.095 pL/mol, respectively) and B max (113.4, 114.5 and 115.3 pmol/L) (Table 3).
Therefore, in response to this comment: Firstly, we have included new data from the SPR binding assay to show the Norrin mutant (R107E/R109E/R115L) in the GAG binding site retains the ability to bind to Lrp6P1E1P2E2.
Interestingly, IntI1 presented a very low affinity for the dsattC in the concentration range where dsattI1×dsattC recombination activity was detected (see fig 1), suggesting that under the reaction conditions, which differed from the binding assay conditions only by the presence of the second dsattI1 fragment, IntI1 can form active complexes on the dsattC.
Taken together, these results show that the αVβ3-specificity claimed for many RGD peptide tracers cannot be concluded from competitive cell binding assay in the U-87 MG model.
That result could be concluded from the filter binding assay with the highest concentration of aptamers available, since there was a large number of bound aptamers.
However, when the tumors were detected at comparatively smaller sizes and highly specific monoclonal antibodies were developed that could detect ERα both in the fresh frozen as well as formalin fixed paraffin-embedded tissues, the clinical labs switched to immunohistochemistry (IHC) from estrogen binding assay for determining the presence of ERα.
Based on our between-study evaluations [ 38], the recent kinase binding assay data from Davis et al. [ 27] seem especially of high quality.
Although this alanine substitution mutant is less stable than the wild type protein, there is no evidence that the Δ31-58 Δ31-58n (Dprotein), which also negatively affected disruption of the phagosome in the CBD-YFP binding assay and decreased escape from the phagosome as seen by electron microscopy is less stable than the whichtype.
Total trichomonad proteins, proteinase-rich extracts, proteins obtained after cell-binding assays from (2 × 10) parasites grown in iron-rich medium, obtained as before [ 7], and TCA-precipitated proteins present in vaginal washes (VWs) (100 μ L) from patients with vaginitis (Table 2) were separated by SDS-PAGE using 10% polyacrylamide gels.
