美国Protein Technologies, Inc. (PTI)     
Protein Technologies,Inc.(PTI)公司位于美国西部风景秀美的度假胜地Tucson，是由美国亚利桑那大学几名科研人员在1985年成立的。经过20多年创业历程，PTI已经发展成为全世界首屈一指的集多肽合成仪制造、多肽合成试剂生产、以及其它相关产品研发及技术支持的大公司。PTI在全球有400多家客户，包括很多著名的大学，例如哈佛大学、耶鲁大学、斯坦福大学、马里兰大学等，还包括像GE、Genetech、Santa等生物技术公司以及众多的制药和多肽合成服务公司。
公司有丰富和强大的产品线，目前已经开发出6款多肽仪产品，有趣的是它们都采用音乐形式来命名。按照设计的先后，这六款产品分别是PS3、Symphony、Sonata、Quartet、Prelude和Tribute。最早的PS3于1985年就设计出来了，而最新的一款Tribute于2007年才上市。我们的客户有科研工作者，也有大型的生产单位。正是由于广大客户的支持，PTI公司才能在开拓市场的同时一直坚持积极的研发和探索，力求把最好的最适合的产品带客户。

客户的需要和建议就是我们的动力，也是公司多年来保持研发创新和蓬勃发展的血液，成为PTI的客户，您好可以享受专业的多肽合成培训、专业的合成方案推荐、专业的品牌服务，以及分享众多客户的经验。PTI是您值得信赖的伙伴和服务者。

Protein Technologies, Inc. (PTI) was founded in 1985 by researchers affiliated with the University of Arizona in Tucson. In 1990, we launched our first peptide synthesizer, the PS3™, and since then we have manufactured and sold the world's finest solid phase synthesizers.

The PS3™ met with immediate success and continues to be one of the most reliable, cost effective, and easy to use instruments on the market.

In 1993 we introduced the Symphony®, a fully automated peptide synthesizer featuring 12 independent reaction vessels that has dominated the multi-channel solid-phase synthesis market. The Symphony® is ideal for custom peptide synthesis because individual reaction vessels may be started, paused, or stopped regardless of what the other reaction vessels are doing, making it equivalent to 12 separate synthesizers in one! The Symphony® is widely regarded as perhaps the finest synthesizer available, and there are hundreds of Symphonys®operating worldwide.

In 1996 we introduced the Sonata®, a large scale automated peptide synthesizer. We included the well-established fluid movement of the Symphony®, as well as its ease of use, reagent optimization, and automated cleavage. We also added a mechanical agitator to assist nitrogen bubbling in order to efficiently mix large amounts of resin in the larger reaction vessels. The Sonata® can produce from grams to near-kilograms of expected product.

In 2000 we introduced the Quartet™, a 4 channel version of the Symphony®. It has all of the advantages of the Symphony® and it can be upgraded to the full Symphony® if the user's needs should grow.

In 2006, we introduced the Prelude™, a 6-channel parallel peptide synthesizer that features no-prime deliveries and extra amino acid bottles for expensive monomer additions. It can also rinse your reaction when an error occurs and send an E-mail status report to your computer or cell phone.

In 2007, we introduced the Tribute™, a revolutionary 2-channel parallel peptide synthesizer featuring a full-color chemical-resistant touchscreen, a 101-position amino acid vial rack, amino acid barcode scanning, fully-adjustable vortex and nitrogen mixing, as well as individual user logging. It also features E-mail notification and washing on error like the Prelude™.

We have built our company on the belief that our products must be the highest possible quality, and we support our products with a dedicated field service team. We are proud of our reputation for reliability and value the trust our customers and partners have placed in PTI. Today we continue to grow and innovate to serve the needs of the peptide synthesis community.
