Major Projects

1. Engineering and expression of poly protein A construct: Two subunits of Protein A, B4 and B5, were engineered to make their octameric units from the monomers using Molecular Biology techniques, PCR, cloning, ligations, sequencing, to name a few. The octameric units were expressed using IPTG and the proteins were purified employing a number of downstream processes. The proteins were run on SDS PAGE gels to check for their molecular size and western blotted to check their binding ability with the IgG antibodies. (Popa Lab)

2. Engineering of fluorophore poly-protein construct: Construct ProteinL- linker-GFP-linker-GFP-linker-ProteinL were constructed employing molecular biology techniques. The construct was expressed and the protein purified. Different concentrations of antibody IgG were run on SDS PAGE gel, western blotted, and incubated in the constructed protein to compare the chemiluminescent signal with the ECL substrate. (Popa Lab)

3. Mutation Analysis and Characterization of Novel Genes in ADPKD Patients: Different combinations of Missense mutation in gene PKD1, directly associated with disease Autosomal Dominant Polycystic Kidney Disease, were analyzed to quantify surface localization of the protein PC-1 in human kidney cells it functions. The clones were created using site directed mutagenesis and transiently transfected into the human kidney cells. The quantification was done using flow cytometry. (Mayo Clinic)
