    摘要： A pricing optimization system can solve a constrained optimization problem by generating one or more prices for one or more items that satisfy a maximum number of prioritized constraints. The one or more generated prices can be one or more prices that represent a minimal deviation between the generated one or more prices and one or more original prices for the one or more items. By satisfying a maximum number of prioritized constraints, and by minimizing a deviation from the one or more original prices for the one or more items, the generated one or more prices are one or more optimal prices.

    摘要： The subject invention relates to a low cost method of producing peptides, including antimicrobial peptides (AMPs), by using microbes. The subject methods enable greatly improved yields of the peptide/AMP as compared to those heretofore known in the art. The subject methods also surprisingly enable the use of Pseudomonas fluorescens to produce AMPs and other peptides. There are several components of the subject invention, which can be used alone or in combination. The subject invention provides for the production of peptides/AMPs in concatemeric precursors. The subject invention also provides novel methods of assembling monomers into multimers, and of cleaving the multimers to yield active monomers. The subject invention also relates to the use of these multimers fused to carrier peptides to produce fusion proteins. Preferably, both the multimers and the fusion proteins (multimers with the carrier polypeptides) lack charge balancing. It has been surprisingly determined that it is not necessary to offset the positive charges of multiple copies of AMPs in multimeric constructs. Thus, the subject invention enables the use of a wider range of multimers and carrier peptides.

    摘要： Anti-peptide antibodies (APAs) are extremely important tools for biomedical research. Many important techniques, such as immunoblots, ELISA immunoassays, immunocytochemistry, and protein microarrays are intrinsically linked to APA function and completely dependent on APA quality. Unfortunately, not all commercially-available APAs have good antigen binding characteristics; as a result, researchers are often unable to perform high quality protein analysis experiments. This disclosure describes a new method for the scalable production of polyclonal APAs using recombinant antigens. These recombinant peptide antigens have several advantages over traditional peptide antigens which improve the ease and speed of antibody production. The recombinant antigens can be scalably produced and purified much faster than traditional synthetic peptide-conjugates. These recombinant antigen-carriers are designed to specifically aggregate in vivo after administration into the host; this aggregation greatly enhances immunogenicity and may eliminate the need for the use of chemical adjuvants which cause physical irritation and discomfort to the host.

    摘要翻译： 抗肽抗体（APAs）是生物医学研究的重要工具。 许多重要的技术，如免疫印迹，ELISA免疫测定，免疫细胞化学和蛋白质微阵列与APA功能本质上相关，完全依赖于APA质量。 不幸的是，并非所有商业上可获得的APA具有良好的抗原结合特征; 因此，研究人员往往无法进行高质量的蛋白质分析实验。 本公开描述了使用重组抗原可扩展生产多克隆APA的新方法。 这些重组肽抗原与传统的肽抗原相比具有几个优点，其提高抗体生产的容易性和速度。 重组抗原可以比传统的合成肽缀合物更快地产生和纯化。 这些重组抗原载体被设计为在给予宿主后在体内特异性聚集; 这种聚集大大增强免疫原性，并且可以消除使用引起身体对主体的刺激和不适的化学助剂的需要。
