Laser flow cytometry is an important tool  for detection and analysis of tumor cells and other cellular markers of diagnostic and therapeutic value. Laser flow cytometry is extensively used for study of cellular proliferation, phenotype  marker expression and  in tumor diagnosis and for monitoring response of cancer patients to therapy. 

The Indo-US Cytometry workshops were initiated in 2001 by Dr. Awtar Krishan from the University of Miami  in collaboration with Dr. Ranbir Sobti of Panjab University, India and Dr. Arvinder Singh of BD Cytometry, India with the express purpose of interfacing Indian researchers with experts in cytometry from abroad. With the collaboration and active support of instrument manufacturers (who provide their latest instruments and staff for the workshops), the Live Education Task Force of the International Society for Advancement of Cytometry (ISAC) and a growing group of core faculty members, a large number of  researchers from all over the world  have been trained in the latest applications of laser flow cytometry in bio-medical research. 

We have used the Indo-US workshop model to conduct workshops in ASEAN countries (Kuala Lumpur, Singapore, Bangkok, Jakarta), Turkey (Istanbul, Marmara, Ankara, Antalya) , Riyadh in Saudi Arabia and in China (Shanghai, Beijing). Similar workshops have also been held in San Diego, Miami, Prague and Glasgow. Future workshops are planned for Chengdu and Hong Kong in China, Cape Town in  South Africa,  Warsaw in Poland, Sao Paulo in Brazil  and  Paris in France.
