INTRODUCTION A major obstacle in the successful treatment of cancer is the development of resistance mechanisms to drug treatment. Various cellular changes that have been implicated in the development of drug resistance in cancer cells include: the increased expressions of P-glycoprotein (a multidrug transport protein) and multidrug resistance-associated protein (MRP-1); increased levels of the cellular detoxification protein‚ glutathione; and changes in the expression of apoptosis associated

No DNA fragmentation occurred in the untreated cells. 3.9. Caspase-3 expression in apoptotic cells The molecular effectors that activate a series of protease that leads to programmed cell death by intrinsic and extrinsic pathways are known as caspases. Caspase-3 dependent apoptotic cell death was induced by Pierisin-6 in human cancer cell lines were . The HeLa

or Maxam/Gilberts sequencing. Introduction The capacity to segregate and amplify individual genes from an intricate genome using recombinant DNA technology technique like PCR has profoundly influenced ways scientists explored the obscurities in biology. Some of the major accomplishments of Recombinant DNA technology include the synthesis of medically essential proteins like insulin and developing new vaccines routes (Kingsman and Kingsman‚ 1988; Primrose et al.‚ 2001). Gene Cloning allows the

By comparing the conformations of uncut DNA with the cut DNA‚ the completed digestion could be verified. Molecular marker‚ which was used for molecular weight calculation‚ was stored in another sample tube. The prepared sample contained puC18 DNA would be run as the degrade DNA control

Expressing and Purifying the Recombinant form of Green Fluorescent Protein (rGFP) from the E.coli strain using Ni2+ agarose affinity chromatography technology Abstract The purpose of this experiment was to express and purify the his6-tagged recombinant form of GFP (rGFP) from the organism E.coli using Ni2+ agarose affinity chromatography. The expression of rGFP was confirmed qualitatively using the UV light and was expressed in the E.coli strain BL21 (DE3) (-- removed HTML --) (-- removed HTML

Historical background is first addressed to contextualize the experiment and define the theories‚ ideas‚ and discussions relevant at the time of the experiment. A brief summary of biologists’ knowledge and attitudes towards bacteria is explained through contemporary quotes. The two main

Marine biologists work hard day in and out to put an end to these terrible things that occur more often that one thinks. Did u know Water covers the 71 percent of the earth.
