Transcription of protein-coding genes can be reconstituted on naked DNA with only the general transcription factors and RNA polymerase II. However, this minimal system cannot transcribe DNA packaged into chromatin, indicating that accessory factors may facilitate access to DNA. One such factor, FACT (facilitates chromatin transcription), interacts specifically with histones H2A/H2B to effect nucleosome disassembly and transcription elongation. FACT is composed of an 80 kDa subunit and a 140 kDa subunit, the latter of which is SUPT16H.

This compact, ergonomic system is an easy to use and accurate solution for high throughput pipetting of 96- and 384-well plates. The PLATEMASTER's 96-channel design greatly reduces the number of pipetting steps necessary to fill a microplate when compared to using regular manual multichannel pipettes. When using this, the time it takes to fill 96-well plates is significantly reduced to approximately 10 to 20 seconds or less, and 384-wells can typically be filled in less than a minute using only four pipetting steps.

Agarose is a purified linear galactan hydrocolloid isolated from agar or agar-bearing marine algae.
Agarose is useful in separation of nucleic acids electrophoretically because agarose gels have larger pore sizes than cross linked acrylamide gels at low concentrations and in chromatographic separations by either beading the agarose or cross-linking it. Agarose gels are also used in immunoelectrophoresis (IEP) and double-diffusion Ouchterlony plates to demonstrate antibody-antigen reactions. Agarose was used to prepare 0.5% agarose gel for Southern blot analysis of the DNA extracted from primate muscles.
The following is a list of properties associated with our agaroses: Sulfate content - used as an indicator of purity, since sulfate is the major ionic group present. Gel strength - the force that must be applied to a gel to cause it to fracture. Gel point - the temperature at which an aqueous agarose solution forms a gel as it cools. Agarose solutions exhibit hysteresis in the liquid-to-gel transition - that is, their gel point is not the same as their melting temperature. Electroendosmosis (EEO) - a movement of liquid through the gel. Anionic groups in an agarose gel are affixed to the matrix and cannot move, but dissociable counter cations can migrate toward the cathode in the matrix, giving rise to EEO. Since electrophoretic movement of biopolymers is usually toward the anode, EEO can disrupt separations because of internal convection.

ZR Plasmid MiniPrep™ Classic is designed for efficient isolation of plasmid DNA from E. coli using a traditional 3-buffer (P1, P2, P3) procedure that is simple, rapid, user-friendly, and reliable. It features a modified alkaline lysis protocol together with a unique fast-spin column to yield high quality plasmid DNA in minutes. The buffers are color-coded (red, green, yellow) for easy determination of complete cell lysis and neutralization. Plasmid DNA purified using this kit is well suited for use in restriction endonuclease digestion, sequencing, DNA ligation, cloning, PCR, bacterial transformation, transfection, etc.
