This invention relates to engineered CH2 domain molecules containing amino acids in the framework regions that confer enhanced stability and/or solubility. In particular, the invention provides engineered CH2 domain molecules containing amino acid residues that differ from a wild type CH2 domain or a template CH2 domain molecule within one or more framework regions and that result in improved stability and/or solubility.

The present disclosure relates to a modified polypeptide of glutamine synthetase having enhanced activity and a method of producing L-glutamine using the same. Since production of L-glutamine may be increased by using the novel modified polypeptide without a decrease in a growth rate compared to wild-type strains having glutamine synthetase activity, the modified polypeptide may be widely used for mass production of L-glutamine.

Kits and methods of using the kits for analyzing macromolecules, including peptides, polypeptides, and proteins, employing nucleic acid encoding are disclosed. The sample analysis kits employ nucleic acid encoding and/or nucleic acid recording of a molecular interaction and/or reaction, such as recognition events (e.g., between an antigen and an antibody, between a modified terminal amino acid residue, or between a small molecule or peptide therapeutic and a target, etc.). Additional barcoding reagents, such as those for cycle-specific barcoding (e.g., “clocking”), compartment barcoding, combinatorial barcoding, spatial barcoding, or any combination thereof, may be included in the kits. The sample may comprise macromolecules, including peptides, polypeptides, and proteins, and the recording may generate molecular interaction and/or reaction information, and/or polypeptide sequence information. The kits may be used in high-throughput, multiplexed, and/or automated analysis, and are suitable for analysis of a proteome or subset thereof.

A method of producing a set of high affinity peptides for detecting one or more antibodies associated with a disease or condition of interest. The method including identifying a set of informative peptides correlated to the disease or condition of interest and translating the set of informative peptides to one or more high affinity peptides for an antibody of interest, wherein the presence of the antibody of interest identifies a subject as having the disease or condition of interest. A diagnostic peptide array produced from the one or more high affinity. A method of detecting an antibody associated with a disease of condition, including: contacting a biological sample with a diagnostic peptide array; and detecting the binding of one or more antibodies to a peptide that is associated with a disease or condition of interest, thereby detecting the antibody associated with a disease of condition.
