Turning Genes On and Off Lab Investigation
Turning Genes On and Off Lab Investigation (Product Code: SLE/EB/16) is a gene-regulation practical used to show how a gene responds to its environment in senior school and college biology labs. A safe, commonly found microbe turns its colonies red when the gene is expressed, so students can predict and then test the effect of temperature simply by looking at the cultures. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as a bacteria culture experiment kit.
Key Details
| Parameter | Detail |
|---|---|
| Type | Gene regulation and expression lab investigation |
| Organism | A safe, commonly found microbe |
| Visible marker | Expression of the gene produces a pigment that turns the bacterial colonies red |
| Main variable | Temperature |
| Extension work | Students design their own experiments to identify other variables that may affect gene expression |
| Shelf life | Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted |
| Product code | SLE/EB/16 |

What Is the Turning Genes On and Off Investigation Used For?
It is used to give students a direct, visible read-out of gene expression. Students grow the microbe at two or more different temperatures, first predicting which conditions will switch pigment production on. Comparing colony colour across the cultures then leads naturally to a discussion of why organisms regulate their genes instead of keeping every gene active all the time. Normal microbiology practice applies throughout: clean technique, clearly labelled cultures and sterilisation of all used material before disposal.
Once the temperature experiment is complete, groups can plan their own follow-up investigations into other variables that might influence expression. In senior classes this makes the investigation a useful bridge to biotechnology lab kit topics such as gene regulation systems and genetic engineering, because students see for themselves that gene activity responds to conditions outside the cell.
Supplier
This investigation is supplied by Jain Scientific Equipments Private Limited, which trades as ScienceLab from Ambala, Haryana, India. Because it involves a living microbe, tell us your practical date when you enquire so that delivery can be planned around the lesson. Details of the company are on our profile page.
Related Laboratory Equipment
Equipment that supports temperature-controlled culture work in this investigation:
- Laboratory Incubator With Visibility Door — holds cultures at a set temperature, and the door lets students check colony colour at a glance.
- Petri Dish — for culturing the microbe at each temperature being compared.
- Thermometer (Digital) — records the actual temperature of each treatment for the results table.
- Autoclave Bag Disposable — for sterilising and discarding used cultures safely.

Frequently Asked Questions
Which organism does the Turning Genes On and Off Lab Investigation use?
The Turning Genes On and Off Lab Investigation uses a safe, commonly found microbe. For its identity and the handling notes that go with it, please contact us before ordering so your lab can prepare suitable culture facilities.
How do students see that the gene is switched on?
In the Turning Genes On and Off Lab Investigation, the gene's product is a pigment, so bacterial colonies turn red when the gene is expressed; no chemical test or special instrument is needed to read the result.
What equipment is needed besides the Turning Genes On and Off Lab Investigation?
Alongside the Turning Genes On and Off Lab Investigation you need a way to hold cultures at different temperatures, such as an incubator, plus standard aseptic items. Ask us exactly what is included so you can plan the rest.
Can students design their own experiments?
Yes. After the temperature experiment in the Turning Genes On and Off Lab Investigation, students can plan their own investigations to identify other variables that may affect gene expression, building experimental design skills.
How should cultures from the investigation be disposed of?
Cultures from the Turning Genes On and Off Lab Investigation should be sterilised together with used consumables, for example in an autoclave bag, before discarding, following your institution's biosafety rules.
How long do the kit's materials keep?
No fixed period is stated for the Turning Genes On and Off Lab Investigation, because shelf life depends on the chemical, its grade and storage conditions. Ask us for the expiry date of the batch you are quoted before scheduling the practical.
Who supplies the Turning Genes On and Off Lab Investigation?
Jain Scientific Equipments Pvt Ltd, trading as ScienceLab from Ambala, Haryana, India, supplies the Turning Genes On and Off Lab Investigation to schools and colleges in India and international markets; shipping arrangements are confirmed in the quotation.
