PIK3R3 (p55 or p55-GAMMA) Antibody

Protein Function

This antibody supports efforts to examine PIK3R3 (p55) and interpret it within interaction networks. PIK3R3 is a pathway component whose activation state and localization can change after stimulation. 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 p55.

Experimental Applications

Parallel measurement of upstream inputs and downstream readouts can sharpen interpretation of pathway behavior. Considering complex membership and compartment shifts can clarify whether changes reflect signaling or redistribution.

Many workflows benefit from tracking both signal intensity and compartment distribution, especially when the target participates in multi-protein assemblies.

Common experimental questions that benefit from target tracking include:

• localization shifts between cytoplasm, membrane, and nucleus
• interaction patterns within multi-protein complexes
• time-resolved changes following stimulation or inhibition

Workflow Perspective

If your project spans exploratory questions, the regular version offers a balanced option for establishing baseline signal behavior. To keep comparisons consistent, align sample preparation steps and define a clear baseline for each series. If interactions are a focus, consider parallel readouts for key partners.

To support downstream analysis, record key context variables (culture timing, stimulation window, and extraction approach) so PIK3R3 patterns can be compared across experiments without guesswork.

Use the regular format version to relate PIK3R3 (p55) behavior to upstream cues and downstream consequences.
