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

Quantitative Analysis of Nitrosamine Impurities by LC-MS Methods from the United States Pharmacopeia General Chapter <1469>

This application note describes the LC-MS-based quantitative analysis of known nitrosamine impurities following procedures 1 and 3 as given in USP general chapter .

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

Bobbitt Group – Professor Product Portal
