There is provided herein, the use of mammalian derived HLA class I molecule for in vitro peptide exchange. For example, there is provided a method of producing an HLA class I molecule complexed to a pre-selected peptide comprising: (a) providing a mammalian derived HLA class I molecule complexed to an existing peptide; (b) incubating, in vitro, the HLA class I molecule complexed to the existing peptide with the pre-selected peptide, wherein the pre-selected peptide is at a concentration sufficient to replace the existing peptide to produce the HLA class I molecule complexed to the pre-selected peptide; and the HLA class I molecule comprises α1, α2, α3 and β2m domains. |

Process for the manufacture of GLP-1 analogues
The present invention provides a process for the manufacture of GLP-1 analogues with high yield and purity by fragment condensation on the solid phase. In particular, it describes a convergent synthesis by condensation of a C-terminal pseudoproline fragment A with a fragment B bound to a solid support, followed by deprotection and cleavage from the support and final purification to yield the desired peptide. The invention further provides intermediates useful in the manufacturing process. |

Dual mass spectrometry-cleavable crosslinking reagents for protein-protein interactions
Described are dual mass-spectrometry-cleavable cross-linkers that can be cleaved selectively using two differential tandem mass-spectrometric techniques such as collision induced dissociation (CID) or electron transfer dissociation (ETD), i.e., a dual cleavable crosslinking technology (DUCCT) cross-linker. When used to cross-link a macromolecule, such as a peptide, MS/MS fragmentation produces two signature complementary mass spectra of same cross-linked peptides, the analysis of which gives rise to high confidence in characterizing the structures of the cross-linked macromolecules as well as sites of interactions. Also described, are methods of making and using DUCCT cross-linkers. |

Proton activated atomic medicine
The present application provides compositions and methods for preparing and using “heavy” nucleotide derivatives of thymidine or uridine by replacing the oxygen atom attached to one or more of positions with non-radioactive oxygen-18 (18O), administering it to a subject to target a tumor including incorporation into tumor cell DNA, and then treating the tumor with proton beam therapy to transmutate the 18O to 18F, resulting in a break of the new fluorine-phosphorous bond. This chemical event destabilizes ribose-phosphate DNA back-bone and base pairing thus produce single- and double strand breaks, clusters lesions that can lead to irreparable DNA damage and enhanced tumor cell killing. The atomic, chemical, and physical aspects result in the use of lower radiation doses and significantly alter acute and late morbidity of radiotherapy. Heavy thymidine and heavy uridine derivatives labeled with 18O have been made and tested. |
