KCNJ5 (Kir3.4 or GIRK4) Antibody - FFPE Validated

Scientific Overview

When control selection matters, this antibody helps you characterize KCNJ5 (GIRK4) in a structured study. KCNJ5 is a membrane-embedded regulator of ionic or osmotic balance in cells. Plan positive and negative controls that match your model system, including perturbations expected to shift the target.

In some datasets and protocols, it is referenced by the gene symbol GIRK4.

Research Relevance

Modulators that affect trafficking, phosphorylation, or ligand binding can change apparent distribution and signal intensity. Time course design can be decisive when regulation is transient or compartment dependent.

Since many cellular processes are coupled, measured differences can reflect both direct regulation and indirect effects from broader state changes.

When building a narrative around the target, it helps to track:

• stimulus-dependent trafficking and turnover
• patterns consistent with apical or basolateral sorting
• relative abundance across engineered constructs

Application-Specific Context

For paraffin-embedded samples, fixation history and retrieval strategy matter; this option is aligned to those constraints. Think about how preparation affects epitope accessibility, and interpret patterns alongside morphology and compartment markers as needed. Align controls to the expected direction of change to support confident interpretation.

For challenging targets, pairing KCNJ5 measurements with a second marker can clarify whether differences arise from regulation, redistribution, or shifts in cell composition within the sample.

Integrate the fixed-section version into your design so KCNJ5 (GIRK4) signals can be interpreted alongside matched controls.
