Microinjection

Posted: Thursday, May 2, 2013

Microinjection uses either a metal needle or a glass micropipette to inject small liquid volumes. For example, genetic material may be inserted into a living cell, a drug introduced into an eye or brain, or fluid injected into a muscle. Typically, microinjection is performed under a microscope.


Recording from Sensory Nerves While Stretching Muscles

Posted: Wednesday, May 1, 2013

This article details how to turn your SI-H muscle research system into one that records the action potentials from the stretch receptors at thesame time that the length and tension of the muscle are recorded.

Nanoliter Troubleshooting

Posted: Wednesday, May 1, 2013

The Nanoliter injector is a micro-processor controlled injection system that uses direct piston displacement. The collet assembly (exploded view) is shown in the image below. The glass pipette fits into the white, plastic sleeve (spacer). When the collet is screwed in place securely, the black rubber washers are compressed and hold the glass firmly in place.


DNA/RNA Quantification Using SPT2 and a Tidas Spectrometer

Posted: Wednesday, May 1, 2013

Concentrations of DNA in solution (31µg/mL and 144µg/mL) were measured with a spectrometer and UV/VIS light source in a SPT-2. Due to the 1cm pathlength, use of a SPT-2 does not require a pre-measurement dilution within this concentration range, thus a potential source of error was eliminated. Due to the design of the SPT-2, routine measurements can be taken with samples of 10µL in standard 200µL PCR tubes. If caution is taken with regard to the location of the probe tip within a PCR via, measurements remain repeatable in sample sizes as small as 5µL.

DNA/RNA Quantification Using DIPUV-Mini and a Tidas Spectrometer

Posted: Wednesday, May 1, 2013

Concentrations of DNA in solution (31µg/mL and 688µg/mL) were measured with a spectrometer and UV/VIS light source in a DIPUV-Mini. Due to the 2mm pathlength, use of a DIPUV-Mini does not require a pre-measurement dilution within this concentration range, thus a potential source of error was eliminated.


DNA/RNA Quantification Using a 2mm Cuvette and a Tidas Spectrometer

Posted: Wednesday, May 1, 2013

Concentrations of DNA in solution (31µg/mL and 561µg/mL) were measured with a spectrometer and UV/Vis light source in a cuvette. A 2mm pathlength cuvette does not require a pre-measurement dilution within this concentration range, thus a potential source of error was eliminated. Although a 2mm cuvette has a total internal volume of 0.7mL, only 350µL is required to obtain an accurate measurement.
