Latherin is a 22 kD (208 amino acids) hydrophobic protein found in equines. It functions as a surfactant protein and has an amino acid sequence that shows similarities to PLUNC (palate, lung, and nasal epithelium) proteins [1]. This protein has been shown to reduce the surface tension of water at concentrations below 1mg/ml [1], and increase the rate of evaporation. Latherin may assist in breaking up microbial biofilms and help limit the buildup of such biofilms on various surfaces [2], and may be useful to study alongside other bio-surfactants such as Surfactant Proteins A, B, C, and D which can be found in the lungs and other areas of the human body. Latherin belongs to an intriguing group of natural surfactant proteins that are bio-compatible unlike current commercially available detergents [3]. The latter are disruptive to cell membranes and also denature proteins resulting in their bio-incompatibility, where Latherin does not. Natural surfactant proteins such as Latherin have critical implications in nanotechnology and the amelioration of effects of oil spills after environmental disasters. Further investigation of Latherin in these contexts will result in new and pioneering inventions in biotechnology 用产品只提供给进一步的科研使用，不可应用于治疗等其他方面。 rPeptide是设在雅典，美国佐治亚州的一家生物技术公司，是一种在阿尔茨海默氏症和帕金森氏病的研究提供研究产品（重组多肽和蛋白质，抗体，试剂）市场的*。rPeptide还提供定制服务的范围从分子生物学，蛋白表达和纯化，13C和15N的多肽和蛋白质的统一标识。 rPeptide有一个专有的平台载体技术，使可溶性肽/蛋白在大肠杆菌中（如淀，β-淀粉样蛋白，瘦素，亲胰岛素）历史上的困难肽/蛋白表达。 商品名称    商品货号    商品品牌 Beta-Amyloid (1-40), Mouse, Rat    A-1007-1    rPeptide Beta-Amyloid (1-40), Starter Kit    A-1150-1    rPeptide Beta-Amyloid (1-40), Starter Kit    A-1150-2    rPeptide Beta-Amyloid (1-40), Ultra Pure, HCl    A-1156-1    rPeptide Beta-Amyloid (1-40), Ultra Pure, HCl    A-1156-2    rPeptide Beta-Amyloid (1-40), Ultra Pure, HFIP    A-1153-1    rPeptide Beta-Amyloid (1-40), Ultra Pure, HFIP    A-1153-2    rPeptide Beta-Amyloid (1-40), Ultra Pure, NaOH    A-1155-1    rPeptide Beta-Amyloid (1-40), Ultra Pure, NaOH    A-1155-2    rPeptide Beta-Amyloid (1-40), Ultra Pure, TFA    A-1001-1    rPeptide Beta-Amyloid (1-40), Ultra Pure, TFA    A-1001-2    rPeptide Beta-Amyloid (1-40, D23N)    A-1013-1    rPeptide Beta-Amyloid (1-40, D23N)    A-1013-2    rPeptide Beta-Amyloid (1-40, F4W)    A-1011-1    rPeptide Beta-Amyloid (1-40, F4W)    A-1011-2    rPeptide
