Detection of Signaling Effector-Complexes Downstream of BMP4 Using In Situ PLA, A Proximity Ligation Assay

BMPs are responsible for a wide range of developmental and biological effects. BMP receptors activate (phosphorylate) the Smad1/5/8 effectors, which then, form a complex with Smad4 and translocate to the nucleus where they function as transcription factors to initiate BMP

Peptide Stability and Potential Degradation Pathways

To prevent or minimize peptide degradation we recommend storing the peptide in lyophilized form at –20 °C or –80 °C. Once in solution, the peptide/protein should be stored frozen in individual aliquots to avoid freeze-thaw cycles. Also, prolonged exposure to
