![]() Incubate at 68 ☌ for 1hr to pre-hybridize.ĭuring pre-hybridization, start the probe transcription reaction. Put cross-linked nylon membrane in the hybridization bottle with the RNA-side up.Īdd 10 ml hybridization buffer (for small hybridization bottle) to the membrane. Nonspecifically bound probes are washed away after hybridization. The probes are then hybridized to the membrane. Use in vitro T7 transcription to make radioactively labeled RNA probes complementary to RNA transcript of interest. Gel can be illuminated with UV to check whether there is any remaining RNA. UV crosslink the membrane twice to fix the RNA on the membrane and use a fine marker to mark the edge of the side with RNA.Ĭlean the gel transfer system thoroughly by rinsing with plenty of H 2O.Īfter the gel transfer, the gel area inside the window of green gasket should be half as thick as the gel outside the window. Dry the nylon membrane between two sheets of filter paper. Remove the gel and take out the nylon membrane. When the transfer is over, remove the sealing frame and drain the buffer. Occasionally check the buffer level to make sure it is above the gel. Place the lid on and transfer for 90 mins at 5 inches of Hg. Gently pour 1 L of 10× SSC buffer into the reservoir. Press the gel and along the window gently to apply extra pressure to help the vacuum sealing. Start the vacuum source and adjust the pressure to 5 inches of Hg. Place the sealing frame on top of the vacuum stage and lock it. Remove all the air bubbles between gel and the nylon membrane. Also make sure the gel overlaps with the gasket by at least 5 mm. Gently place the gel on top of the gasket with the well-side up. Make sure the gasket covers the seal o-ring while the membrane/filter paper overlaps with the window of the gasket. Place the plastic gasket on top of the membrane/filter paper. Wet the seal o-ring on the base unit with H 2O. Make sure there is no air bubble between membrane and filter. Place the wetted nylon membrane on top of the filter paper. Put wet filter paper on the vacuum porous stage and make sure the filter paper is in the area where the cut window of the green plastic gasket is going to be. Wet the nylon membrane and filter paper first in H 2O and then 10× SSC buffer Cut a filter paper with the same size as the nylon membrane.įill the wells of the RNA gel with melted agarose. Biofilm formation on polystyrene was positively correlated with biofilm formation on stainless steel and with resistance to quaternary ammonium compounds, a group of disinfectants.RNA is transferred from gel to nylon membrane using vacuum gel transfer system.Ĭut a nylon membrane about (or bigger than) the size of the denaturing RNA gel. Northern blot analysis indicated that the expression of the ica genes was higher in strong biofilm formers compared to strains not forming biofilms. The icaA gene was partly sequenced for 22 food related strains from nine different species of Staphylococcus, and their icaA genes were found to have a DNA similarity of 69-100% to previously sequenced icaA genes. The presence of icaA was positively correlated with strong biofilm formation. The icaA gene of the intercellular adhesion locus was detected by Southern blotting and hybridization in 38 of 67 food related strains tested. The biofilm forming strains belonged to nine different coagulase negative species of Staphylococcus. Glucose and sodium chloride stimulated biofilm formation. Seven and 21 of 144 food related strains were found to be strong and weak biofilm formers, respectively. In the present work staphylococci from the food industry were found to vary widely in their ability to form biofilm on polystyrene. Biofilm formation may also be of importance for survival and virulence in food related staphylococci. In clinical staphylococci presence of the ica genes and biofilm formation are considered important for virulence.

![]() It represented the first click, but note the volume control does not use step increments and is smooth with no clicks. I did detect at the very bottom of the volume control, but only at the highest gain level that the right side would come in before the left side but at that volume level, I doubt anyone will find the amp useful and most certainly will never use this amplifier at that volume level. This multi-track potentiometer promises excellent channel matching even at low volume levels which have always been an issue with analog potentiometers. ![]() IFi decided to go fully analog even at the volume control level and the ZEN CAN employed a Japanese made Tokyo Cosmos electric company analog volume control. ![]() The amplifier section is also a dual mono design in where each channel has its own 4 stages but 2 separate circuits operate left and right channel outputs.ĭual mono designs are usually reserved for top-tier amplifiers and never seen at this price point especially with a class A circuitry. The iFi ZEN CAN have a discrete 4 stage amplifier design, using an output chip at every stage and each stage represents a 6 decibel gain. Other features of this class A proprietary circuitry is a FET single-ended input stage ensuring loading of the source and always maintaining a constant Class-A operation. Performance-wise their rated distortion levels are at 0.0001% and that is a lot of zeros. These Op-amps are an iFi exclusive component and are the same class A discrete output buffers used on the Pro ICan. Part of the circuitry in the iFi ZEN CAN use their German code-named ‘Operationsverstarker’ custom made IFI/AMR J-FET OV2637A Op-amps. Even on the single-ended side, you could power up some very hungry cans. This is enough power for basically any headphone out there. The balanced output side can output 1890mw at 64 ohms. iFi was able to squeeze out a very respectable 15.1 volts at 300 ohms. Running in constant class A, the ZEN CAN is capable of 1600mw at 32 ohms on the single-sided output. It seems this is a feat that was achieved well by iFi with no heat sinks or fans and no apparent ventilation whatsoever. The ZEN CAN employs basically the same class A discrete power output stage as the Pro iCAN.Įvery class A amplifier produces lots of heat because of the nature of the design but iFi managed to get this one to run just slightly warm. IFi borrowed lots of technology from their flagship $1700 Pro iCAN and used it to produce the ZEN CAN. On top of that, they offer it at a very low price of just $169. ![]() iFi seems to have taken all the technology they have, except for the kitchen sink as they say, and incorporated it into the ZEN CAN. Sure there have been lots of changes but they all seem to be for the better.Ī perfect example is their new ZEN CAN. Their components seem to get less and less expensive with each model but pack just as many features as the previous models. IFi has also gone through a shift in style, concept, and even value lately. They also gave us their own unique balanced headphone input and output topology. They have given us many unique features like XBass, S Balanced, IE match, proprietary circuitry, and custom components. There is no doubt in my mind that iFi is a company that loves to innovate and push boundaries. ![]() 308 ammunition is not only the world’s most accurate, but the closely matched ballistic trajectories between different projectile types increases its tactical effectiveness for the operator.308 Winchester is probably the most versatile centerfire rifle caliber today, and capable of outstanding accuracy.

That load with a jacketed bullet, weighing 220 grs, I expect to see, between 1040-1100fps with the average barrel, custom tube maybe 1120fps. I shoot a lot of Sierra 125 and 150 SPT in my 308s using reduced loads of H4895 for general target practice and informal 100yard matches at club. Lapua is the world leader in providing match grade projectiles in this caliber, offering several types of Ball, Open-Tip, Armor Piercing, Solid, and Subsonic bullets. This versatility is the reason the caliber remains the most popular choice for use in law enforcement and military sniping applications. 308 Winchester (7.62x51mm NATO) possesses mild recoil, good terminal ballistics, and an effective range of 800 meters (875 yards). with the 13.0 g (200 gr) FMJ Boat Tail Subsonic tactical projectile ![]() Super easy to use - create the activity, enter URL & title and save.Please contact us to learn more about it.
