Disclosed herein are systems and methods for producing recombinant proteins utilizing mutantstrains containing expression vectors carrying nucleic acids encoding the proteins, and secretory signal sequences to direct the secretion of the proteins to the culture medium. Host cells transformed with the expression vectors are also provided.

An adapter for use with a hand-held electronic device for use in detecting the optical properties of a sample. The adapter includes a backing plate having an integral surface that secures the adapter to the electronic device. The adapter also includes a sample housing having a sample holder and a cap. The sample holder is configured to receive the placement of a sample and/or a sample vessel. The backing plate includes an orifice that allows the passage of light from the sample to the detector of the electronic device. The backing plate may also include another orifice that allows for light emitted from an emitter of the electronic device to enter into the sample holder. The sample holder may also include reflective surfaces that direct light to/from the sample as well as filters that filter the wavelength of light sent to sample and/or detected by the detector.
