In the present study recombinant VP3 (rVP3) was expressed in E. coli BL21 (DE3) (pLysS) and its polyclonal antibodies were characterized. SDS-PAGE analysis revealed that the expression of recombinant protein was maximum when induced with 1.5 mM IPTG for 6 h at 37 degrees C. The 6xHis-tagged fusion protein was purified on Ni-NTA and confirmed by Western blot(More)
Cancer is one of the major causes of death worldwide. In spite of achieving significant successes in medical sciences in the past few decades, the number of deaths due to cancer remains unchecked. The conventional chemotherapy and radiotherapy have limited therapeutic index and a plethora of treatment related side effects. This situation has provided an(More)
BACKGROUND & OBJECTIVES The conventional techniques used in TB diagnosis like AFB (acid fast bacilli) smear microscopy lack sensitivity and the gold standard, culture test takes time. A test based on multiplex polymerase chain reaction (PCR) targeting the 38 kDa gene and IS6110 insertion sequence, specific to Mycobacterium tuberculosis was developed to(More)
Live cell imaging enables the study of dynamic processes of living cells in real time by use of suitable reporter proteins and the staining of specific cellular structures and/or organelles. With the availability of advanced optical devices and improved cell culture protocols it has become a rapidly growing research methodology. The success of this(More)
Rapid emergence of drug resistance in Mycobacterium tuberculosis (MTB) is a major health concern and demands the development of novel adjunct immunotherapeutic agents capable of modulating the host immune responses in order to control the pathogen. In the present study, we sought to investigate the immunomodulatory effects of G1-4A, a polysaccharide derived(More)
Hemagglutinin neuraminidase (HN) is a membrane protein of Newcastle disease virus (NDV) with the ability to induce apoptosis in many transformed cell lines. TNF-α is a multi-factorial protein that regulates cell survival, differentiation and apoptosis. In a previous study, we reported that HN protein induces apoptosis by downregulating NF-κB expression.(More)
Liver-enriched transcription factors (LETF) play a crucial role in the control of liver-specific gene expression and for hepatocytes to retain their molecular and cellular functions complex interactions with extra cellular matrix (ECM) are required However, during cell isolation ECM interactions are disrupted and for hepatocytes to regain metabolic(More)
