During Postgraduate studies good experiences obtained in handling of experimental animals (especially Rattusnorvegicus), sterilization of laboratory tools and equipment, in vitro cell culture techniques (including isolation of cells, trypsinization, subculture, three dimensional culture in metrigel, steroid & protein hormones stimulation, fixation and RNA extraction from the cell pellets, cryopreservation), ELISA, imunohistochemistry, western blotting, RT-PCR , operating bioanalyzer (using Agilent 2100) and sequencing techniques (using MegaBACE sequencing instrument, USA).
He identified novel correlation between Prolactin and IGF-I by means of exogenous leptin treatment on In-vitro model. Further he concluded that Biological effects of leptin on the rat endometrium include dose- and time-dependent stimulatory effects on stromal cell PRL secretion. Also he identified expression of leptin receptor isoforms in relation to female reproductive cycle.
Later he worked very briefly as a postdoctoral fellow with Prof.K.H.Tennekoon at IBMBB. He has gained significant experience in the microarray techniques and managed to optimize the major steps of the cDNA microarray protocols. He was involved in optimizing various intermediate steps such as primer annealing, cDNA synthesis, degradation of mRNA template, purification of cDNA, coupling cDNA with CyDye NHS ester, purification of CyDyelabeledcDNA, preparation of cDNA for hybridization and etc.
Dr.Eswaramohan has been supervising jointly with Professor S.N.Surendran, Department of Zoology for postgraduate students on various aspects on Malaria, Dengue and Leishmania related research.
Further he has actively been collaborating with Dr.A.Murugananthan in scorpion molecular taxonomy by means of DNA, sequencing technology and venom analysis by SDS-PAGE. This is a collaborative research at Department of Parsitology, Faculty of Medicine, University of Jaffna.
He is also collaborating in another study on “The prevalence of cutaneous leishmaniasis, its causative Leishmania species and possible animal reservoirs for the vector in Hambantota District”, with Department of Zoology, University of Ruhuna, Matara, Sri Lanka.
