GRIA3 (GluR3 or GluA3) Antibody - Western Blot Validated

Biological Background

This antibody supports efforts to assess GRIA3 and interpret it within interaction networks. GRIA3 is a trafficking-sensitive transporter that can shift between intracellular pools and the plasma membrane. Many projects interpret this target alongside interacting partners, upstream cues, and downstream readouts.

In some datasets and protocols, it is referenced by the gene symbol GluR3.

Use in the Laboratory

Modulators that affect trafficking, phosphorylation, or ligand binding can change apparent distribution and signal intensity. Considering complex membership and compartment shifts can clarify whether changes reflect signaling or redistribution. Neural differentiation and synaptic organization projects may include this target as a contextual readout.

Depending on the model, researchers may ask whether signal shifts reflect altered abundance, compartment changes, or remodeling of associated complexes.

To keep datasets interpretable, labs often document:

• relative abundance across engineered constructs
• stimulus-dependent trafficking and turnover
• surface versus intracellular pool distribution

Version Notes

When samples are prepared in reducing conditions, some epitopes become more accessible; this version is designed with that context in mind. If your study compares multiple conditions, keep acquisition and processing settings stable to avoid confounding.

For challenging targets, pairing GRIA3 measurements with a second marker can clarify whether differences arise from regulation, redistribution, or shifts in cell composition within the sample.

The denaturing-format option supports mechanistic reading of GRIA3 when interactions and context are the focus.
