Important information about our service - Please read

  • Our microinjection service prices have increased (from February 2024): Go here for more information
  • All you need to know: Go here for detailed information about our microinjection service (including sample shipment and payment).
  • Sample preparation: Sample quality is the major factor that determines the success or failure of microinjection work. Please read our guidelines for sample preparation before sending your samples for microinjection.
  • Microinjection request form:Find our Microinjection Request form here
  • Injection-only requests from outside the UK: We no longer accept injection-only requests (e.g. Plans 1, 4, 6, 8) from outside the UK. This is because we are uncertain whether shipping from the UK to the EU will be efficient enough to ensure the viability of injected larvae.
  • Free repeat injections: Our offer of a free injection only applies to repeats of the original injection with, perhaps, minor modifications (freshly prepared sample, change of host stock etc.). It is not a credit for future injection requests.
  • VAT payments: Our microinjection service does not qualify for medical VAT-exemption. All Purchase Orders covering microinjection requests from research groups in the UK (outside of Cambridge University) must include VAT at 20%.
  • Microinjection service enquiries: Please direct enquiries to flyinject@gen.cam.ac.uk, this address reaches Alla Madich (Microinjection Technician), Glynnis Johnson (Senior Research Technician) and Simon Collier (Fly Facility Manager).

 

P-element / piggyBac transformation

Plan 1

Inject 200 embryos - provide surviving larvae

£160 ex VAT

£192 inc VAT

Plan 2

Inject 200 embryos – provide unbalanced G2 transformants. Plan 2 takes at least 4 weeks from injection to completion

£225 ex VAT

£270 inc VAT

Plan 3

Inject 200 embryos – provide balanced lines. Plan 3 takes at least 8 weeks from injection to completion

£310 ex VAT

£372 inc VAT

  • For Plans 1-3, we will inject into white1118 embryos unless you request otherwise.
  • For Plans 2 and 3, we will provide a minimum of 5 independent transgenic lines, unless your insert is large (i.e. more than 13kb). If we fail to generate 5 or more independent lines, we will offer you the option of a repeat injection at no additional cost. 
  • Plan 1 is injection only, we do not normally offer a free repeat if no transformants are obtained.
