MYTH allows the sensitive detection of transient and stable interactions between proteins that are expressed in the model organism Saccharomyces cerevisiae. It has been successfully applied to study exogenous and yeast integral membrane proteins in order to identify their interacting partners in a high throughput manner.

Hybridization of Atomic Orbitals I

The mathematical expression known as the wave function, ψ, contains information about each orbital and the wavelike properties of electrons in an isolated atom. When atoms are bound together in a molecule, the wave functions combine to produce new mathematical descriptions that have different shapes. This process of combining the wave functions for atomic orbitals is called hybridization and is mathematically accomplished by the linear combination of atomic orbitals. The new orbitals that...

Whole-Mount In Situ Hybridization

Whole-mount in situ hybridization (WMISH) is a common technique used for visualizing the location of expressed RNAs in embryos. In this process, synthetically produced RNA probes are first complementarily bound, or "hybridized," to the transcripts of target genes. Immunohistochemistry or fluorescence is then used to detect these RNA hybrids, revealing spatial and temporal patterns of gene expression. Unlike traditional in situ hybridization techniques, which require thin tissue sections whose...

sp3d and sp3d 2 Hybridization To describe the five bonding orbitals in a trigonal bipyramidal arrangement, we must use five of the valence shell atomic orbitals (the s orbital, the three p orbitals, and one of the d orbitals), which gives five sp3d hybrid orbitals. With an octahedral arrangement of six hybrid orbitals, we must use six valence shell atomic orbitals (the s orbital, the three p orbitals, and two of the d orbitals in its valence shell), which gives six sp3d 2 hybrid orbitals.

FAQs
Stringent washing separates probe molecules paired with the intended target from probes retained through nonspecific interactions. Its role is therefore not simply cleanup: it helps preserve the sequence specificity of the measured signal. In practice, the final result depends on whether complementary pairing remains detectable after washing, which strengthens interpretation of a positive signal.
Immobilization keeps the nucleic acid population fixed on a solid membrane so it can be exposed to the probe and washed without losing the target from the assay. Denaturation separates paired strands, making complementary sequences accessible for probe pairing. Together, these steps create a stable, readable format for sequence-specific detection.
The same sequence-specific pairing principle can be applied to different nucleic acid targets. In Southern blotting, the approach supports gene identification and analysis of DNA organization, whereas in Northern blotting it supports assessment of RNA abundance. This distinction makes the technique useful across both DNA-focused and RNA-focused questions in biology.
A meaningful signal depends on several linked choices: the probe must be complementary to the sequence of interest, incubation conditions must promote that pairing, and washing must remove nonspecific interactions without eliminating the intended complex. The probe's label then makes the retained interaction measurable. These factors jointly affect how confidently the signal can be assigned to a particular sequence.
Once washing has removed nonspecific interactions, a retained labeled signal provides evidence that the membrane contains a sequence complementary to the probe. The result can therefore support gene identification or sequence-specific validation, rather than serving as a general measure of all nucleic acids present. Interpretation depends on the probe-target pairing and the preceding wash conditions.
Membrane Hybridization is useful when a study requires sequence-specific information from DNA or RNA immobilized on a membrane. Applications described for the technique include identifying genes, examining DNA organization, assessing RNA abundance, and studying genetic variation or gene expression. It is also valuable for validating sequence-specific results, giving researchers an additional way to examine molecular findings.
By detecting selected DNA or RNA sequences with complementary probes, the method connects a molecular signal to a defined genetic target. That makes it relevant to studies of genetic variation when DNA organization or sequence identity is being examined, and to gene expression studies when RNA abundance is assessed. Its value lies in targeted validation, not an untargeted survey.
