   1.What are the main applications of Bronchogen?

   
   

   Bronchogen is a lung-targeted regulatory peptide widely used in respiratory tissue repair research, airway inflammation mechanism study, lung health raw material development and biochemical laboratory testing. It participates in preclinical research related to pulmonary epithelial regeneration and respiratory injury recovery, and is a popular research raw material for respiratory protection formula trials.

   2.How to store Bronchogen to keep its activity stable?

   
   

   Bronchogen is sensitive to temperature, light and moisture. Short-term storage needs sealed preservation at 2–8°C in dry and dark environment; long-term storage should be kept below -20°C away from damp and repeated temperature changes to avoid biological activity decline.

   3.What payment methods do you accept?

   
   

   We support multiple flexible payment options, including  corporate bank transfers, Alipay, WeChat and WISE. We can also create a dedicated payment link for you, which supports credit card, Apple Pay, and Google Pay. You may pick the one that works best for you.
