General Guidelines
Follow these guidelines when using ig 10B chemically competent E. coli.

• Handle competent cells gently as they are highly sensitive to changes in temperature or mechanical lysis caused by pipetting.
• Thaw competent cells on ice, and transform cells immediately following thawing. After adding DNA, mix by tapping the tube gently. Do not mix cells by pipetting or vortexing.

Protocol

• Remove competent cells from the -80 °C freezer and thaw completely on wet ice (10-15 minutes).
• Aliquot 1-5 µl (1 pg-100 ng) of DNA to the chilled microcentrifuge tubes on ice.
• When the cells are thawed, add 50 µl of cells to each DNA tube on ice and mix gently by tapping 4-5 times. For the pUC19 control, add 1 µl of (10 pg/µl) DNA to a chilled microcentrifuge tube, prior to adding 50 µl of cells. Mix well by tapping.
• Incubate the cells with DNA on ice for 30 minutes.
• After 30 minute ice incubation, heat shock the cells at 42 °C for 45 seconds.
• Transfer the tubes to ice for 2 minutes.
• Add 950 µl of Recovery Medium or any other medium of choice to each tube.
• Incubate tubes at 37 °C for 1 hour at 210 rpm.
• Spread 50 µl to 200 µl from each transformation on Pre-warmed selection plates.
• Incubate the plates overnight at 37 °C.

ReadyStrain™ II Sterile Cell Straining Kits

Harvest is the first product of its kind, providing all the necessary parts for filtration of cell suspensions and combining them into a single, preassembled, ready to use, sterile packet. The kits eliminate the contamination risks associated with opening multiple packages, and assembling separate pieces. The individual sterile packets mean researchers are no longer forced to expose entire bags of 50mL tubes and corresponding caps to perform one filtration. Instead they can open a single ReadyStrain packet directly under the hood.
  

• Kit Includes: strainer, 50 mL tube & cap
• Opens directly under the hood reducing risk of contamination
• Pre-assembled - ready to use
• Guaranteed sterile - gamma
• Packaged in easy-open "tear-strip" bags

10 Layer BioFactory™ Culture Chambers with Tube 

Recombinant proteins from MIDSCI are expressed in a Pichia Pastoris (yeast) system which provides many advantages for research. Excellent bio-activity at an exceptional value. IBI recombinant proteins are lyophilized and are shipped at room temperature.

ADVANTAGES

• Extensive line of animal (including mouse & rat) and human proteins.
• All proteins are expressed in a Yeast system providing many advantages.
• 100% of the protein purchased is active and usable.
• No endotoxins produced in a yeast system.
• Yeast expression promotes protein folding making product more like its native host.
• Post-translational modifications promote greater bio-activity.
• Proteins are expressed and purified without HIS-TAGS or any other TAGS.
• Proteins are lyophilized and shipped without a carrier protein.
• Excellent quality and value when compared to other products expressed in E. coli.

APPLICATIONS

• Basic immunology (human)
• Veterinary Immunology
• Vaccine Research
• Cell culture proliferation
• Species focused research for human diseases.
