Application
DMSO is a polar aprotic solvent used in chemical reactions, in polymerase chain reactions (PCR) and as a cryoprotectant vitrification agent for the preservation of cells, tissues and organs. DMSO is used in cell freezing media to protect cells from ice crystal-induced mechanical injury. It is used for frozen storage of primary, sub-cultured, and recombinant heteroploid and hybridoma cell lines; embryonic stem cells (ESC), and hematopoietic stem cells. DMSO is frequently used in the combinations with BSA or fetal bovine serum (FBS).

DNA Fingerprinting – Electrophoresis Education kit
Login to see pricesBrand:
Cleaver Scientific
Our DNA fingerprinting kit is the perfect tool to introduce students to the world of electrophoresis and forensic science. DNA fingerprinting is a laboratory technique used to establish a link between biological evidence and a suspect in a criminal investigation. A DNA sample taken from a crime scene is compared with a DNA sample from a suspect. If the two DNA profiles are a match, then the evidence came from that suspect. Conversely, if the two DNA profiles do not match, then the evidence cannot have come from the suspect.
Each kit contains DNA, agarose gel, electrophoresis buffer and DNA stain enough for 8 groups of students to cast and run the experiment and visualise the DNA separation. The gel takes approximately 5 minutes to load, 30 minutes to run and 15 minutes to stain, meaning the whole experiment can be completed in a one hour lesson, with convenient incubation periods for scientific discussion and teaching. Students will solve a crime using an unknown DNA sample from the crime scene and a series of suspects!
Key Features
- Perfect for 1 hour lessons
- Introduce students to DNA and forensic science
- Works perfectly with Cleaver Scientific equipment
DNA Kit

Cleaver Scientific
This simple kit will enable you to teach the principles behind gel electrophoresis. The kit contains five DNA samples labelled A to E, two of which are identical, with enough reagents to run two sets of six gels. The students will be able to run their own agarose gel and view the DNA after the samples have migrated through the gel. The DNA samples can be viewed on a standard UV transilluminator or using the totally sage blue light LED devices.
DNase agar 500g

Thermo ScientificTM OxoidTM
Detect microbial deoxyribonuclease enzymes, particularly from staphylococci, with Thermo Scientific™ Oxoid™ DNASE Agar (Dehydrated). A DNase (deoxyribonuclease) is any enzyme that catalyzes the cleavage of phosphodiester linkages of DNA leading to its degradation. The organisms producing DNase enzymes in sufficient quantities to hydrolyze DNA will show clear zones around the colonies. The medium is mainly used in the identification of staphylococci but may also be used for the detection of DNase activity in other organisms.
DNASE Agar, Oxoid Composition
| Typical Formula* | gm/litre |
| Tryptose | 20.0 |
| Deoxyribonucleic acid | 2.0 |
| Sodium chloride | 5.0 |
| Agar | 12.0 |
| pH 7.3 + 0.2 |
DNASE Agar, Oxoid Preparation:
Suspend 39g in 1 litre of distilled water and bring to the boil to dissolve completely. Sterilise by autoclaving at 121°C for 15 minutes.
Storage conditions and Shelf life
Store the dehydrated medium at 10-30°C and use before the expiry date on the label.
Store the prepared plates of medium at 2-8°C.
Precautions
The DNase reaction for staphylococci is an indication of pathogenicity, it cannot be used as the sole criterion for identification.
Small zones of clearing may be caused by other enzymes or organic acid production.
Other organisms than staphylococci, Serratia and aeromonads can produce DNases.
Once the hydrochloric acid has been applied to the medium the plate must be read within a few minutes and further testing cannot be carried out by re-incubation.
The methyl green must be purified by extraction with chloroform.
Toluidine blue varies in performance according to source.
Merck Toluidine blue 1273 is satisfactory. Note that this dye cannot be used for Gram positive organisms.

Cleaver Scientific
Four different sample number, size and style of Hybridisation Manifold are offered; two types of Dot Blotter and two types of Slot Blotter. Typical applications include clone screening with DNA/RNA probes in Southern/Northern blots and immunological screening with antibodies in Western blots. The units incorporate precision lapped surfaces to ensure uniform blotting membrane contact and a leak proof gasket. These prevent lateral transfer of samples and smudging by ensuring that a complete vacuum is formed. Six thumbscrews ensure even and tight sealing for fast sample suck down.
