巴西采购需求：氨基酸、氨基酸衍生物和肽试剂

I'm reaching out to inquire about the wholesale pricing for your range of enzymes. We are exploring options for sourcing high-quality enzymes for our upcoming projects and would love to understand your pricing structure better. Could you please provide detailed information on your wholesale rates, including any bulk purchase discounts, minimum order quantities, and shipping terms? Additionally, if you have any product catalogs or specifications available, that would be greatly appreciated. Thank you!
