Alamanda Polymers是世界领先的多聚氨基酸生产商，其主要产品为多聚寡氨基酸链以及PEG化的多聚氨基酸链。其拥有独特的多聚化工艺，是唯一能够提供确切的聚合数值多聚氨基酸的公司，能够使研究者的实验结果更加具有可重复性。

Alamanda Polymers specializes in the manufacturing of well-defined polyamino acids for research laboratories doing work in gene therapy, encapsulation, drug delivery, cell adhesion, and surface coating. Our company provides a wide range of metal-free biopolymers including homopolyamino acids and PEGylated polyamino acids. Due to our characteristic polymerization process, we are the only supplier able to offer effectually exact polyamino acid chain lengths thereby giving researchers new options for use and consistently reproducible results.

Alamanda Polymer has more than 15 years experience in the synthesis of polyamino acids, has developed a polymerization process that enables them to have complete control over the molecular weight of our polyamino acids without the use of metal catalysts. Furthermore, not only does the process enable us to achieve effectually exact chain lengths but also highly monomodal products (polydispersity index: 1.01-1.2) and batch-to-batch consistency.
