Company History
Cetus was founded in 1971 by Ronald E. Cape, Peter Farley, and Nobelist Donald A. Glaser. They started by developing automated methods to select for industrial microorganisms that could produce chemical feedstocks, antibiotics, or vaccine components.
The company's early efforts laid the groundwork for the biotechnology industry, which was revolutionized by the development of recombinant DNA, monoclonal antibodies, and gene expression in the late 1970s. Cetus raised $108 million in an initial public offering (IPO) in 1981, the largest IPO at that time.
Cetus' first large development project was the cloning, expression, modification, and production of beta-interferon, in conjunction with Triton Biosciences. Unfortunately, the resultant protein did not live up to its expectations as a broad-spectrum anti-cancer drug.
Here are some key dates in Cetus' history:
- 1971: Founded by Ronald E. Cape, Peter Farley, and Donald A. Glaser
- 1981: Raised $108 million in an initial public offering (IPO)
- 1991: Sold to Chiron Corporation
History
Cetus was founded in 1971 by Ronald E. Cape, Peter Farley, and Nobelist Donald A. Glaser. They initially focused on developing automated methods to select for industrial microorganisms that could produce greater amounts of chemical feedstocks, antibiotics, or vaccine components.
In the late 1970s, three revolutionary techniques were developed: recombinant DNA, monoclonal antibodies, and gene expression, which formed the foundation of the biotechnology industry. Cetus was quick to adapt to these new fields.

The company raised $108 million in an initial public offering (IPO) in 1981, the largest IPO to date. This significant investment helped Cetus enter the new fields of biotechnology.

Elusive Business Plan
The elusive business plan - a concept that's been the bane of many an entrepreneur's existence. It's a crucial document that outlines a company's goals, strategies, and financial projections, but it can be a daunting task to create one.
One of the key challenges in developing a business plan is defining the company's mission and vision. For example, in our company's history, the founders struggled to articulate a clear mission statement that would guide the company's direction.
A well-crafted business plan should include a detailed analysis of the market and industry. This involves researching competitors, identifying target audiences, and understanding market trends. Our company's market research revealed a significant gap in the industry for innovative solutions.

A business plan should also outline the company's financial projections, including revenue models, expense budgets, and cash flow projections. The founders of our company had to make some tough decisions about how to allocate resources and manage expenses.
A good business plan should be flexible and adaptable to changing circumstances. It's not a static document, but rather a living, breathing guide that evolves as the company grows and learns. Our company's business plan has undergone several revisions over the years to reflect changes in the market and industry.

Mass Screening System
The Mass Screening System was a crucial part of Cetus Corporation's operations. It was a biotechnology system used for microbiology strain improvement.
In 1973, the Cetus Mass Screening System (CMSS) was developed, and I was part of the team that supported it. We started with a computer center and developed software to support the system.
The CMSS included an isolate assay analysis program, an isolate production vs time database storage and retrieval system, and an isolate production analysis program. These programs played a vital role in the system's functionality.

As the project progressed, we also interfaced a large agar plate laser scanner to the center's PDP-11 digital computer. This allowed for the scanning and analysis of large arrays of assay tests on each plate.
The scanned data preprocessing and analysis program was developed to discern the inhibitor zone sizes of the assay tests. This was a critical step in the system's operation.
With the CMSS in place, Cetus Corporation was able to improve its microbiology strain development capabilities. This marked an important milestone in the company's growth and development.
Author's Experience
I joined Cetus Corporation in 1973 as one of the initial 20 employees, starting out as the manager of the computing facility supporting the Cetus Mass Screening System.
My first job involved developing software support for CMSS, including creating an isolate assay analysis program and an isolate production vs time database storage and retrieval system.
In 1975, my role was nearing completion, but I was then asked to consider the instrumentation and control activities supporting CMSS.
Serial Dilution Machine Development
I spent several weeks working on the development of a serial dilution machine, which is essentially a device that can accurately and efficiently dilute various substances to precise concentrations.
The machine's design was inspired by the concept of serial dilution, where a single stock solution is repeatedly diluted to achieve the desired concentration.
