  DNA Techniques Kit

After attending a Department of Biological Sciences workshop, participants are eligible to request science kits containing all the materials, supplies, and equipment required to perform workshop protocols with their students at no cost to the teacher or school district.

Five DNA Techniques Kits are available. Kit contents may also be individually tailored for specific needs and goals as determined by discussion between the teacher and the Outreach Coordinator or the DNA Techniques Director upon receipt of the Kit Application Kit Application.

Recombinant DNA

In this protocol, DNA plasmids with ampicillin and kanamycin resistance genes are cut, then religated together in an attempt to form a plasmid containing the resistance genes for both antibiotics. NOTE: Recombination protocol also requires Bacterial Transformation materials.

Materials

  • 0.2 mg/ml pAMP (for ligation)
  • 0.2 mg/ml pKAN (for ligation)
  • 0.1 mg/ml pAMP (for undigested control)
  • 0.1 mg/ml pKAN (for undigested control)
  • 2X restriction buffer
  • Bam HI/Hin dIII enzyme mix
  • Agarose
  • 1X TBE electrophoresis buffer
  • Ethidium bromide
  • 6X gel dye
  • DNA standards for gel
  • 10X Ligation buffer
  • 10X ATP
  • Sterile water
  • T4 DNA Ligase
  • 0.5 ml microfuge tubes
  • Micropipettors and sterile tips
  • Microcentrifuge
  • Vortexer
  • Heat block at 37C and 65 C
  • Flasks for melting agarose
  • Graduated cylinder
  • Small gel electrophorisis boxes with power supplies
  • Polaroid camera and film
  • Protocols

BacterialTransformation

The transformation protocol may be used along with the recombinant DNA protocol, or as a separate experiment. Bacteria may be transformed with plasmids containing antibiotic resistance genes, or the pGLO plasmid that gives ampicillin resistance along with the green fluorescent protein gene allowing the bacteria to glow in the presence of UV light and arabinose sugar.

Materials

  • DNA for transformation: 0.005 mg/ml pAMP, pKAN, and/or pGLO
  • Competent E.coli cells
  • Sterile LB broth
  • Agar plates: LB, LB/AMP, LB/KAN, and/or LB/AMP/Ara
  • Micropipettors and sterile tips
  • Latex gloves
  • 15 ml push-cap culture tubes
  • Ice buckets
  • Heat blocks at 37 C and 42 C
  • Plate spreaders
  • Plating ethanol
  • UV light box (for pGLO transformation)

DNA Isolation/Restriction Digest/Electrophoresis

In this protocol, plasmid DNA is isolated, then digested with restriction enzymes and electrophoresed in order to observe banding patterns. Alternatively, plasmid DNA can be provided for the restriction reaction, or plasmid DNA may be provided as digested and undigested samples that are ready to load onto a gel.

Materials for DNA Isolation

  • 5 ml sterile LB broth in culture tubes
  • Agar plates containing bacteria colonies (to start cultures)
  • GTE solution
  • SDS/NaOH solution
  • KOAc solution
  • Isopropanol
  • 70% ethanol
  • TE buffer

Materials for DNA Restriction and Electrophresis

  • Plasmid DNA
  • 5X Restriction buffer
  • Bam HI/Hin dIII enzyme mix
  • Sterile water
  • Agarose
  • 1X TBE electrophoresis buffer
  • Ethidium bromide
  • 6X gel dye
  • DNA standards for gel
  • Micropipettors with sterile tips
  • Latex gloves
  • 1.5 ml microfuge tubes
  • Eppendorf 5145C mini centrifuge
  • Vortexer
  • Microcentrifuge
  • Flasks for melting agarose
  • Graduated cylinder
  • Gel electrophorisis boxes with power supplies
  • Polaroid camera and film
  • Protocols

PCR Amplification of D1S80 Locus

This protocol may be used as part of a "crime solving" demonstration. The polymerase chain reaction amplifies DNA at the D1S80 locus---a noncoding region on chromosome 1 composed of 16 base pair repeats that can display heterozygous or homozygous phenotypes.

PLEASE NOTE: DNA preparation and gel electrophoresis may be performed in the school lab, but the PCR reactions must be done at the Oakland campus due to limited availability of thermocycler required for this protocol.

Materials

  • Sterile 0.9% saline solution
  • 1X PCR buffer
  • 10% Chelex resin
  • Proteinase K
  • PCR master mix
  • 25 mM MgCl2
  • Taq DNA Polymerase
  • 6X gel dye
  • Nuseive 3:1 agarose
  • 1X TBE electrophoresis buffer
  • Ethidium bromide
  • DNA standards for gel
  • Paper cups
  • Micropipettors and tips
  • Latex gloves
  • 2.0, 1.5, and 0.5 ml microfuge tubes
  • 0.2 ml PCR tubes
  • Vortexer
  • Microcentrifuge
  • Graduated cylinder
  • Flasks for melting agarose
  • Eppendorf 5145C minicentrifuge
  • Heat blocks at 65oC and 102oC
  • 11 x 14 gel electrophoresis units with power supply
  • Polaroid camera with film
  • Protocols

Extraction of DNA from calf thymus

This kit utilizes simple houshold ingredients to extract DNA from calf thymus cells. It allows students to see DNA spooling.

Materials

  • Thymus cells
  • Meat tenderizer
  • Woolite detergent
  • Ethanol
  • Blender
  • 500ml beaker
  • Spatula
  • 16x150 test tubes
  • Wooden sticks
  • Spoon
  • 25ml and 50ml plastic pipets
  • Pipet racks
  • Pipet helper
  • 60C water bath
  • Protocols
