Please join us at Exhibit 219 for further information about our products and services:

• Multiplex arrays for indoor allergens (MARIA¢â) on the Luminex xMAP¢ç system
• DUSTREAM¢â environmental samplers
• LoTox¢â low endotoxin purified allergens
• ELISA products, rapid tests

Join us for a demonstration of MARIA¢â technology, which enables 8 allergens to be measured in a single test - one test, multiple assays!

Scientists from INDOOR Biotechnologies have several oral and poster presentations at AAAAI.

MARIA¢â - Multiplex ARrays for Indoor Allergens using Luminex xMAP¢ç technology

MARIA¢â represents the next generation of ELISA and combines Indoor Biotechnologies allergen- specific monoclonal antibodies with the power of Luminex xMAP¢ç technology to measure eight allergens at once in a single test. MARIA¢â provides improved assay performance (increased sensitivity, accuracy and precision) in a high throughput system with substantial time and cost savings.

Customers can choose from two kits, each containing pre-mixed microspheres, as follows:

• 5-plex: Der p 1, Der f 1, Mite Group 2, Fel d 1, Can f 1 (Product Code MRA-P5)
• 8-plex: Der p 1, Der f 1, Mite Group 2, Fel d 1, Can f 1, Rat n 1, Mus m 1, Bla g 2 (MRA-P8)

Custom combinations of bead sets are available. For a limited time, custom 5-plex arrays will be the same price as our standard 5-plex. Standard discounts (15%) are applied to orders of five or more kits.

MARIA¢â kits and services are available exclusively through Indoor Biotechnologies. For full details, see: www.inbio.com/maria

Indoor Biotechnologies recently introduced a Universal Allergen Standard (UAS) that contains eight purified natural allergens from dust mite, cat, dog, rat, mouse and cockroach [UAS pdf]. The UAS is designed for use in both ELISA and MARIA¢â. From January 2008, the UAS is provided in ELISA and MARIA¢â kits.

To assist customers in changing to the UAS, Indoor Biotechnologies has implemented a free vial replacement program. Under this program, vials of ELISA allergen standards in ELISA kits that were purchased after July 1, 2007 will be replaced free of charge with one vial of the UAS for each ELISA kit purchased.

To take advantage of this offer customers should provide: invoice or other documentation of ELISA kit purchase; number of ELISA kits purchased; ELISA kit product codes; and number of replacement vials being requested. US customers should contact: mail@inbio.com : other customers should contact our UK office at: info@indoorbiotech.co.uk.

DUSTREAM¢â collectors are essentially phthalate and endotoxin free. In response to customer enquiries, our plastics company has checked with the three manufacturers whose products are used in DUSTREAM¢â: DOW Chemical, Clariant Corp., and Basell Polyolefins. DOW and Clariant do not use phthalates in their manufacturing processes. The phthalate concentration of Basell resins is less than 25ppm: in contrast, plastics that require phthalate plasticizers contain up to 500,000ppm phthalates. Documents are on file to confirm these specifications. We also have data indicating that the surface endotoxin levels on the collectors are undetectable.

Based on these data, INDOOR Biotechnologies believes that DUSTREAM¢â collectors can be reliably used for environmental sampling to determine exposures to phthalates and endotoxin.

Need to know more about indoor allergens, allergic disease and environmental exposure assessment? We will again be holding our successful training course in Charlottesville, September 8-10, 2008. Join us for the course on "Health Effects of Indoor allergens, Molds and Endotoxin: Theory and Practice". The conference includes a distinguished list of invited speakers:

Elizabeth Matsui MD: Allergens and asthma in inner cities
Matt Perzanowski PhD: Endotoxins in allergic disease - a plus or minus?
Herman Mitchell MD: Environmental risk factors for asthma and their control

This year the program features multiplex array technology for allergen detection (MARIA¢â). Participants will be the first to gain hands-on experience of this powerful technology for allergen exposure assessment. The course provides an excellent opportunity to learn in a relaxed and informal setting. Charlottesville in September is delightful and we are an easy two hours drive from Washington DC.

The conference is limited to 40 participants. Please register to reserve your place(s) as soon as possible.

INBIO Training Course - Preliminary Announcement

Acaba de aparecer un compendio del conocimiento actual sobre enfermedades alergicas en espanol: el Tratado de Alergologia. Esta obra surgio como una iniciativa de la Junta Directiva de la Sociedad Espanola de Alergia e Inmunologia Clinica, con la intencion de agrupar y reflejar, en una unica obra, el conocimiento actual en este campo y facilitar su estudio. La obra, editada por los Drs. Antonio Pelaez e Ignacio J. Davila, ha sido patrocinada por Glaxo-SmithKline y publicada por la editorial Ergon. Tal como los editores mencionan en el prologo a la primera edicion, el Tratado "viene a llenar una laguna existente en la literatura medica en espanol". A modo de introduccion al Tratado de Alergologia, y con el permiso de la SEAIC, GSK y Ergon, presentamos el primer capitulo sobre Alergenos (pulsar).
