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

限制性内切核酸酶 — 分子剪

术语“限制酶”源自Werner Arber和Matthew Meselson实验室对肠杆菌噬菌体λ（λ噬菌体）的研究。

氧化铁（IO）纳米颗粒由磁赤铁矿（γ-Fe2O3）和/或磁铁矿（Fe3O4）颗粒组成，直径范围在1到100纳米之间，可用于磁性数据存储、生物传感和药物运输等领域。

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
