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

西格玛奥德里奇细胞培养_细胞分析_计数检测-默克生命科学

细胞增殖是生物体生长、发育、繁殖以及遗传的基础，是生物体的重要生命特征。检测细胞在培养基或组织中的生长速率，对于细胞生长和分化研究至关重要。在药物开发过程中也常被用于评估药物的毒性和对癌细胞生长的抑制情况。
