WB Analysis of Restricted Smad Protein Phosphorylation

Predicted vs observed Smad2 Phospho Ser250 WB band size
The viewpoint that Western blot analysis represents the gold standard for detecting cellular signaling events is absolutely correct. This is particularly true when examining restricted smad protein phosphorylation patterns in research applications. TGF-β superfamily ligands control critical cellular processes through serine-threonine receptor kinases. These signaling pathways activate specific type I receptors that target distinct transcription […]

Western Blot Confirms High-Mobility Group Boxes-RB Interaction

Comparison of amino acid sequences of different HMGBs
The interaction between High-Mobility Group Box proteins and retinoblastoma protein represents a critical breakthrough in cancer biology. Recent research demonstrates that this protein-protein interaction serves as a fundamental mechanism for tumor suppression. Western Blot analysis provides definitive evidence of this molecular relationship. We have identified HMGB1 as a key tumor suppressor that directly binds to […]
