1 GFP overview
Rating
0.0 stars

In this program, we'll look at the production of Green Fluorescent Protein. GFP is used as a biological marker, and when attached to a drug it can provide researchers with a visual story of where the drug goes. It's a fluorescent dye that's very well tolerated by most cells and doesn't interfere with normal cellular function. Let's examine the 3 main phases of GFP production – Fermentation, Recovery, and Purification. Fermentation is basically cell farming. We program cells to produce a product, we nurture them as they grow and reproduce, and then we harvest them. In recovery we separate our product from the cells where they were housed. And then in purification we go a step further by removing everything else that's contaminating our product leaving us with a very pure, concentrated solution.

2nd Centrifugation (GFP Recovery part 4 of 5)
Rating
0.0 stars

After the second homogenization, the lysed cell solution is pumped back through the centrifuge. But this time, our goal is different. Before lysing, our product was held within the E.coli cells. Now – with the cells broken apart, the cell contents - including cytoplasm and GFP - are mixed into the buffered solution. The centrifuge again spins out the solids - which are primarily cell debris - and it's the clarified liquid which contains our product – the GFP! This time we discard the solids and keep the liquid – which is now known as Lysate.

The 4 Phases of Fermentation (GFP Fermentation part 1 of 6)
Rating
0.0 stars

Different cells have different needs. Some are aerobic – they need oxygen – while others are anaerobic and don't need oxygen. But the lifecycle of almost all cells follows a predictable 4 phase-pattern. Lag, Exponential, Stationary and Death. When a cell is first introduced to fresh growth media, it has to adapt to the new environment. This creates a lag in the growth timeline. After the organism adapts, the batch takes off. The cells begin dividing at a constant rate –an Exponential or Logarithmic increase. But eventually, the nutrients in the media are consumed, toxic metabolic waste products build up, cells begin to die, and growth slows. When just as many cells are dying as are dividing, the batch enters the Stationary phase. This is the point at which the key nutrients are completely consumed, the fermentation is stopped and the broth is harvested. If the fermentation were allowed to continue, the cells would enter the Death phase.

Anion Exchange Chromatography (GFP Purification part 2 of 6)
Rating
0.0 stars

The Purification process begins as the transfer tank of clarified lysate from the Recovery process is connected to the inlet pump on the Chromatography skid. The first Chromatography step in our GFP purification process is Anion-Exchange. At this point in the process, the pH of the clarified lysate is about eight-point-zero, which means that the protein is negatively charged. Because it is negatively charged, GFP will bind to the positively charged anion exchange resin. The pump draws the lysate from the vessel...past the first conductivity sensor and pressure sensor...and through the zero-point-four-five micron pre-filter. The pre-filter removes any residual cell debris or other particulates that may have contaminated the solution. If the pre-filter begins to clog, the pressure sensor at the inlet side of the filter will register a rising pressure...and the controller will signal the need for a filter change. After pre-filtering and before the column, the lysate passes through a flow meter... and an air sensor. Then, as the lysate passes over the resin beads, the negatively charged protein attaches to the positively charged beads. The solution leaving the column passes a UV optical density sensor, a conductivity sensor and a pH sensor. The optical density sensor's low readings confirm that the GFP is not in the solution, so the outlet valve sends the solution to waste.

Applying a Simple Stain to a Bacterial Culture
Rating
0.0 stars

Applying a simple stain to a bacterial culture is a technique that is used for examining the size, shape, and arrangement of a specimen. It uses a dye to stain the cells, making them easier to see under a microscope. In this experiment, we will demonstrate the steps for applying a simple stain to the bacterial organism, staphylococcus. Our hope is that after viewing this video, you will feel more confident and be better prepared to try applying a simple stain in a hands-on lab experience.

Aseptic Gowning for the Cleanroom
Rating
0.0 stars

One of the primary safeguards that life science companies use to help prevent contamination in cleanroom operations is Gowning. Gowning is basically putting on clothing -- in this case layers of specially designed garments, covers, masks and gloves -- that isolates your body from the clean room environment. Gowning is more involved than just slipping on a coverall and going to work. Gowning is itself a process, with carefully sequenced steps to ensure that your body is fully covered, and that the protective garb remains free of contamination. In this video, we'll demonstrate the top-down approach for both general and aseptic gowning.
