Reliability and Validity

Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways. Unfortunately, being consistent in measurement does not necessarily mean that you have measured something correctly. To illustrate this concept, consider a kitchen...

This experimental protocol demonstrates the use of virtual prism adaptation therapy (VPAT) in healthy adults and the association between VPAT and functional near infrared spectroscopy to determine the effect of VPAT on cortical activation. Results suggest that VPAT may be feasible and could induce similar behavioral adaptation as conventional prism adaptation therapy.

Scalable High Throughput Selection From Phage-displayed Synthetic Antibody Libraries

2015
A method is described with visual accompaniment for conducting scalable, high throughput selections from phage-displayed combinatorial synthetic antibody libraries against hundreds of antigens simultaneously. Using this parallel approach, we have isolated antibody fragments that exhibit high affinity and specificity for diverse antigens that are functional in standard immunoassays.
FAQs
Confidence comes from agreement among complementary controls, not from a strong signal alone. A positive control shows that the assay can reveal the target, whereas a negative control indicates whether signal persists without the expected target or recognition context. Comparing both controls with relevant samples helps separate target-dependent detection from nonspecific binding and supports more defensible interpretation.
Orthogonal validation strengthens an antibody claim by testing the same target with a different analytical approach. Genetic loss-of-function controls add a direct test: when target expression is reduced or eliminated, a genuine antibody signal should change accordingly. Agreement across these independent lines of evidence is especially useful when a single assay could confuse nonspecific binding with recognition.
Validation must be matched to the sample and assay in which the antibody will be used. Signal observed in one relevant sample does not automatically establish reliable performance in another, so target-dependent behavior should be examined across the intended material. This comparison matters when studying host immune responses or pathogen-associated proteins, where inaccurate detection can distort biological conclusions.
A practical workflow begins by selecting positive and negative controls, then measuring the antibody in relevant samples under the planned assay format. Investigators compare signal patterns, examine whether detection depends on the target, and, when needed, add an orthogonal method or genetic loss-of-function control. The resulting evidence guides whether the antibody is suitable for the planned measurement.
Antibody validation is particularly important before immunoblotting, immunofluorescence, flow cytometry, or immunohistochemistry. Each application uses antibody-based detection to generate measurements, so unsupported signal can affect comparisons among samples and experiments. Validation evidence helps researchers decide whether results from a selected assay can be used to characterize immune responses or detect pathogen-associated proteins.
In immunology and infection studies, validated reagents improve comparability between experiments and strengthen conclusions about host responses and infectious disease biology. They can support detection of pathogen-associated proteins and comparison of experimental results, while reducing the risk that antibody behavior rather than biology explains an observed difference. This makes validation a reproducibility step, not merely a preliminary technical check.
