美国IB(Indoor Biotechnologies) 
IB公司是一家专业开发生产用于研究哮喘以及其他过敏性疾病的免疫诊断和相关生物学检测产品的生物技术公司，IB由两家子公司组成，一家是位于美国弗吉尼亚的INDOOR Biotechnologies Inc. (IBI)，另一家为位于英国INDOOR Biotechnologies Limited (IBL)。IB的创始人Martin D. Chapman博士曾经是美国弗吉尼亚大学的医学和微生物教授，并曾经担任过美国NIH、环保署已及多家生物公司的顾问科学家。做为环境过敏原（变应原）检测系统的领导公司，IB生产的一系列过敏原研究和检测用抗体拥有来自美国弗吉尼亚大学的独家专利，能够用于检测屋尘螨、猫、狗、蟑螂和真菌来源过敏原。

IB开发生产面向实验室用户的过敏原Elisa检测试剂盒以及面向家庭用户的过敏原快速检测试剂盒，利用后者用户在家中即可于10分钟之内检测出屋尘螨抗原。这些检测系统可用于对过敏原环境暴露水平的评估，也能让用户对使用的过敏原隔离清除程序、相关产品和设备的有效性进行可靠的评估，还可应用于过敏原标准化以及相关产品的研究开发。

Indoor Biotechnologies (IB) is an immunodiagnostics and biotechnology company specializing in manufacturing innovative products for investigating environmental and immunologic aspects of asthma and allergic diseases. The company's technology includes a comprehensive set of monoclonal antibodies for the detection of house dust mite, cat, dog, cockroach and fungal allergens.

IB has a worldwide exclusive licence to market these antibodies from the University of Virginia Patent Foundation. IB has developed a range of innovative allergen detection systems, including laboratory based ELISA and a consumer based rapid test kit, which detects mite allergen in the home within 10 minutes. These systems provide a complete range of tests for assessing environmental exposure to indoor allergens; for testing the efficacy of allergen avoidance procedures, products and devices, for allergen standardization and product development.

IB is the world leader in environmental allergen detection systems. IB technology is used worldwide and has been reported in over 250 scientific publications on indoor allergens. IB operates an INDOOR?Allergen Analysis Service, Contract Research Services and Professional Training Courses. IB introduced natural and recombinant allergens as a new product line for research use and for developing new strategies for allergy diagnosis and treatment. This range of products currently includes the most important dust mite, cat and cockroach allergens. IB has an extensive product pipeline and ambitious plans for developing consumer based allergy diagnostic devices and environmental products.

IB was founded by Dr. Martin D. Chapman, formerly Professor of Medicine and Microbiology at the University of Virginia and a member of the UVA Asthma and Allergic Diseases Center. Dr. Chapman is a Fellow of the American Academy of Allergy, Asthma and Immunology and has served as a consultant to the U.S. National Institutes of Health, the Environmental Protection Agency, and several biotechnology and environmental products companies. IB is organized as two affiliated companies, INDOOR Biotechnologies Inc. (IBI), located in Charlottesville, Virginia, USA, and INDOOR Biotechnologies Limited (IBL) based in Warminster, UK. IBI carries out research, development and sales in the Americas and IBL handles sales, distribution and business development in Europe, the Far East, Australia and New Zealand.

IB还开发出了天然和重组的过敏原产品线，可用于研究和开发新的过敏原诊断和过敏性疾病的治疗策略，目前包括最重要的屋尘螨、猫和蟑螂来源的主要过敏原。

IB的技术和产品已经在全球范围内被广泛使用，相关的科学论文已在超过250种科学出版物上发表。除提供产品以外IB还提供过敏原分析服务、合同研究服务以及专业培训服务。
