The mannose-6-phosphate/insulin-like growth factor 2 (M6P/IGF2) receptor is a transmembrane protein with the ability to sequester growth factors from the extracellular matrix. This behavior links the receptor to tumor suppression. On a structural level, the extracellular portion of the protein is segmented into 15 homologous repeats, which can be divided further into 5 triplet domains, labelled 1-3, 4-6, 7-9, 10-12, and 13-15. Each triplet receptor displays its own unique ligand binding affinity, including the ability to form dimers with triplets on a second M6P/IGF2 receptor. In fact, previous studies indicate that this protein functions optimally when dimerized. Thus, the purpose …

A low-cost spectrometer was designed for the purpose of teaching spectroscopy. The spectrometer can be built by the student and contains interchangeable pieces such as slit width, grating, and lenses. This will allow the student to understand how changing these variables effects resolution. The spectrometer was constructed from PVC pipe, a plastic electrical box, and a USB webcam. The actual resolution of the spectrometer is close to the theoretical value, depending on which lens and grating is used. In addition, an extra piece can be added that allows absorption spectra to be collected. Having the student piece together the spectrometer …
