Various chemistries have been used to attach DNA probes to filters, but most involve a carboxyimide coupling using 5'-aminomodified nucleosides placed directly on the surface with a mechanical micropipet
. Other methods depend on initially modifying the surface with a stable aliphatic poly linker followed by attachment using standard phosphoramidite chemistry (4).
Other items required include a thermal cycler, gel electrophoresis equipment, and micropipets
Immediately after the Hg vapor exposure on GD18, blood was drawn from the tail of four females in each group into hepa-rinized calibrated micropipets
(Drummond Scientific Co., Broomall, PA).
Danish medical technology developer MediCult A/S announced on Thursday (26 April) an agreement to acquire US micropipets
supplier Humagen Fertility Diagnostics Inc (Humagen) in a USD22.9m cash deal.
Preparation and use of needles and micropipets
for handling very small particles.
We layered 5 [micro]L of CS and HS calibrators (0.5-5.0 /,g) with micropipets
to construct calibration curves.
(Previously, everything had been prepared for them, and they weren't allowed to use the micropipets
.) Because the instructor acted as a facilitator during the laboratory session, students interacted with, rather than feared, the instructor.
