As a professional manufacturer and supplier of P21 peptide powder, Company Xi'an Faithful BioTech Co., Ltd has always focused on providing high-purity and high-quality steroid raw materials. We rely on advanced production equipment, strict quality control system and senior R&D team to ensure that each batch of products meets your R&D and production requirements accurately. We are always committed to providing customers with stable and reliable product supply and efficient and professional technical support to help your enterprise and R&D continue to grow and succeed.
P21 peptide is a synthetic bioactive polypeptide, usually composed of 21 amino acid sequences, with clear molecular structure and functional specificity. It is widely used in basic research and drug development in the fields of molecular biology, pharmacology and cytology, and plays a key role in frontier topics such as cell cycle regulation, stem cell differentiation, anti-aging and neuroprotective mechanism.
It is usually prepared by solid phase synthesis , with high purity, low endotoxin and good batch consistency. P21 peptide powder shows high stability and biocompatibility in vitro and in vivo experiments, and is suitable for cell culture, protein interaction research, animal experiments, drug screening and other experimental scenarios.
In order to maintain its biological activity and the reliability of experimental results, attention should be paid to solubility (it is recommended to use sterile distilled water or buffer solution for dissolution), it is recommended to keep it dry and dark at-20 C and experimental operation specifications.
