Vision To be the premier BioResource Center for dust mites in Asia.
Motto When you think of dust mites, Think of SDMC, Thailand
Missions 1. Maintain the cultivation of dust mite cultures 2. Provide the dust mites to researchers / industries 3. Develop the testing services for anti-mite products regarding consumer protection 4. Conduct the research study focusing on dust mites 5. Make the collaboration with academic and private sectors to share knowledge on dust mites aspects
Establishment of Dust mite cultures
The way from laboratory cultures to BRC 1997 1998 2002
SDMC 2002 - Present
4 weeks Using mite isolator Purity 99% Harvestation
Allergon, Sweden SDMC, Thailand Microscopic Physical Appearance CSL, UK Greer Lab, USA
Uses of Dust Mites Dust Mite extracts: for diagnostic / therapeutic purposes Biological study: climate control, growth rate, Taxonomic study: genetic identification,. Testing anti-mite products: mite proof, herbal acaricides etc.
Quality Assurance of Dust Mite Product Pre-culture Culturing Post-culture Mite strains Food/Media Containers Planning Mite strains Contaminations Growth rates Environment Correct species Purity Waste management Stock management
Good Dust mite products Single species 99% purity High yield Dermatophagoides pteronyssinus Dermatophagoides farinae Blomia tropicalis

Quality Improvement On-going process to improve the quality system to be accredited against ISO 9001: 2008 requirements. Tentative Date of Accreditaion => February 2014
Research
Asian Pac J Allergy Immunol 2012;30:224-30 To detect multiple target genes by using multiple primers Simultaneously identitied 3 mite species in one reaction High specificity and high sensitivity
Specificities Lane 1 : 0.1 ng DP + 10 ng DF (1:100) Lane 2 : 0.1 ng DF + 10 ng DP (1:100) Lane 3 : 0.1 ng BT + 10 ng DP (1:100) Lane 9 : 0.1 ng each of DP, DF, BT Lane 10 : 10 ng each of DP, DF, BT Lane 5 : 10 ng DP + 0.1 ng DF (100:1) Lane 6 : 10 ng DF + 0.1 ng DP (100:1) Lane 7 : 10 ng BT + 0.1 ng DP (100:1)
Sensitivities 1 mite => 10 ng gdna
