PR1MA™ T4 Gene 32 Protein

 

PR1MA™ T4 Gene 32 Protein (T4 gp32) is a single-stranded DNA binding (ssDNA) protein required for E. coli bacteriophage T4 replication. It binds and stabilizes ssDNA structures which facilitates electron microscopic examination, and has also been shown to improve restriction digests, improve T4 DNA polymerase activity, and increase the yield of PCR reactions, including those with long amplicons. 

  • Optimal temperature: 37°C
  • Heat inactivation: 65°C for 20 minutes
  • Storage temperature: -20°C
  • 10X T4 gp32 reaction buffer included

Buffer composition

  • 50% glycerol
  • 50 mM Tris-HCl
  • 50 mM KCl
  • 1 mM DTT

Freedom Rocker™ BotBlot® 

 

The Freedom Rocker™ BlotBot® is an automated blot processor. The fully programmable blot processing station automates the tedious incubation and washing steps required to process blots and gels, thus saving time and money through increased productivity. All trays receive the same reagent or wash buffer at the same time, in equal volumes, ensuring consistency.

Simply dispense individual reagents (in volumes as low as 3.5 mL) into appropriate trays and recover them separately. This allows the conservation of primary antibodies. The control panel has a large graphic display and intuitive layout making it easy to program protocols. These protocols can include different rocking speeds and times for each step. 

BlotBot® with a clear window can be employed when using reagents that are not light-sensitive in western blots. BlotBot® with a blackout window is recommended when using fluorescent reagents in western blots to preserve their integrity.

  • Automated delivery and removal of buffers/reagents
  • Dispense and recover different antibodies or reagents in each tray
  • Only 3.5 mL or reagent per blot is needed due to specially designed trays
  • Reagent recovery
  • Easy to use-just plug in
  • Quiet, no air or vacuum connections necessary
  • Drip-proof quick-release connections
  • 2-year warranty

Benchmark™ BenchWaver™ 3-D Rocker

  • Adjustable speed & tilt for a wide range of applications
  • Large 13 x 13.5 in. work surface
  • Insta-TILT™ technology for instant adjustment to the tilt angle
  • Dual platform accessory doubles work surface
  • Cold room and incubator safe

The BenchWaver™ combines the basic rocking motion of traditional platform rockers with the circular motion of orbital shakers. This combination is ideal for generating the optimum 3-dimensional undulating motion commonly preferred for molecular biology applications.

The tilt angle is instantly adjustable from 0 to 10 ° and the mixing speed can be adjusted from 5 to 105 rpm, using the large, user-friendly LCD control panel. Combined control of both parameters (tilt and speed) makes the BenchWaver™ a versatile workhorse that can provide anything from gentle, slow-moving waves to rapid more vigorous motion. Additionally, the time of operation can be selected from 1 minute up to 99 hours for continuous operation.

The large 13.5 X 13 In. platform is supplied complete with a non-slip rubber mat. An optional stacking platform is available for users requiring additional mixing capacity. BenchWaver™ is a reliable and versatile instrument and can be used in refrigerated or incubated environments, from +2°C to +60 °C.

Optional stacking platform and dimpled rubber mat available.

SealPlate® RollMate™ Pre-scored Film

Convenient, Easy-to-Use Roll format.

Pre-scored film on a roll is a more economical and efficient alternative to rapidly seal microplates or racked test tubes; faster than applying single sheeted film.

Continuous backing liner can be torn off or fed directly into a waste basket for disposal.
  • Economical
  • Quicker, more efficient sealing
  • Provides a secure seal and is easy to remove
  • Rigid polyester film features good clarity and easy handling
  • Can be used as a temporary seal while awaiting further processing
Applications
  • General laboratory use
  • Short-term storage
  • Incubation
  • ELISA
Temperature Range
  • -40°C to +120°C

EZcap™FoilStrips

An economical and more user-friendly alternative to PCR strip caps; no sore thumbs and fingers guaranteed!

Application: PCR and light sensitive assays
Temp. Range: -20°C to +120°C

Precision cut to a smaller dimension for sealing one PCR 8-tube strip or a single row of a 96-well PCR or deep-well storage plate whenever rows must be
selectively protected or accessed. FoilStrips remove easily with no splash back as can occur with strip-caps.
  • Certified DNase- & RNase- free
  • Each sheet contains 6 strips on a continuous liner for ease of use
  • Pierceable with a pipet tip or robotic probe for direct sample recovery
  • The conformable nature of foil allows for the visual verification of the seal’s security around each well
  • 2.0 mil aluminum foil removes easily without tearing 
Helpful Tips:
  • A non-locking workstation is recommended for sample prep (e.g. 96-well round-boom plate)
  • Removal of the end-tabs at the perforations is recommended before cycling
  • A final sealing step is highly recommended in the thermal cycler because 8-tube strips flex during handling
  • Do not fold foil around sides of tubes

With a 50 uM layer of acrylic adhesive that withstands cold storage at temperatures to -80 °C.

Unlike other sealing films in the AlumaSeal® group, AlumaSeal® CS™ sealing films are not recommended for PCR or thermocycling. A single non-perforated end tab simplifies application. Simply hold the tab and strip the backing from the body of the sealing film as it lays on the plate to avoid curling. Dimensions are 82.6 by 132.6 mm, including the single 9.5 mm end tab. AlumaSeal® CS™ sealing films are certified DNase-, RNase-, and nucleic-acid-free.
  • Specially formulated for cold storage to -80 °C
  • Excellent barrier properties to retard evaporation
  • Easily pierceable with pipet tips or robotic probes for sample recovery 
*Completing application of AlumaSeal® CS™ sealing films by pressing with the accessory plate roller assures a secure uniform seal around all wells.
