Tetraspanin-28 (TSPAN28 or CD81) Antibody - Western Blot Validated

Protein Function

Plan your comparisons around Tetraspanin-28 and use this antibody to characterize state-dependent differences. Tetraspanin-28 is a cell-surface or matrix-associated protein that mediates adhesion and outside-in signaling. 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 CD81.

Experimental Applications

Comparative experiments can separate expression differences from changes in adhesion structure abundance. Time course design can be decisive when regulation is transient or compartment dependent.

In practice, target tracking can support localization mapping, relative quantification, and interaction-focused experiments without locking you into a single readout strategy. In oncology research models, expression shifts can accompany changes in adhesion, signaling, or differentiation state.

Common experimental questions that benefit from target tracking include:

• remodeling after changes in substrate or mechanical stress
• focal adhesion versus diffuse membrane distribution
• effects of adhesion inhibitors or matrix composition

Workflow Perspective

When samples are prepared in reducing conditions, some epitopes become more accessible; this version is designed with that context in mind. To keep comparisons consistent, align sample preparation steps and define a clear baseline for each series. Predefine acceptance criteria for controls before collecting the full dataset.

For challenging targets, pairing Tetraspanin-28 measurements with a second marker can clarify whether differences arise from regulation, redistribution, or shifts in cell composition within the sample.

Use the denaturing-format option to keep Tetraspanin-28 analysis aligned with planned contrasts and endpoints.
