MBEC Assay® Kits Product FAQ

Which product would you recommend I use?

We recommend the MBEC Assay® Biofilm Inoculator with 96 well bases to most customers.  It is useful for many commonly used bacterial species such Acinetobacter spp., Escherichia spp., Klebsiella spp., Staphylococcus spp., some streptococcus spp., Proteus spp., Pseudomonas spp.Salmonella spp., and Enterobacter spp.

The MBEC Assay® Biofilm Inoculator with 96 well base & Hydroxyapatite is used to simulate bone/teeth, so we recommend this product for dental pathogens (Streptococcus mutans, Fusobacterium nucleatum, and Porphyromonas gingivalis).  Hydroxyapatite coated pegs typically result in greater biofilm growth compared to uncoated pegs, so we also recommend the MBEC Assay® Biofilm Inoculator with 96 well base & Hydroxyapatite for strains that form weaker biofilms (Candida, CitrobacterEnterococcus faecalisListeriaNocardia, fungus, yeast, and anaerobic strains).

The trough base is recommended for strains that prefer the side-to-side flowing against the MBEC Assay® pegs rather than the rotary motion; this typically works well with plant pathogens.

If you are uncertain about which product to order, contact info@innovotech.

What is the difference between the 96 well bases and the trough based products?

The 96 well base has separate wells which allow you to test different strains in different wells. The trough base doesn’t have separate wells, it’s a tray with open longitudinal rows where inoculated media would flow from side to side on a rocker shaker, which only allows one strain per plate.

We sell the MBEC Assay® Kits with 96 well bases to 95% of our customers. The trough base is mainly used for plant pathogen strains, where we need larger fluid volume flowing against the pegs.

What is the minimum order for the MBEC Assay® plates? And is there any discount for large orders?

Minimum order is a case of 10 MBEC Assay® plates, prices vary between the regular and the coated MBEC Assay® plates. Academic institutions get a 10% discount on all MBEC Assay® products. Additional discounts may be available for large orders. Click here for prices

What type of ultrasonic cleaners do you recommend?

Any ultrasonic cleaner should work.  This is an example of the ones available from VWR:
https://us.vwr.com/store/product/12626090/vwr-ultrasonic-cleaners-220v;jsessionid=CypugE60bBCOtLmyua3WwYnn.estore4a. The size of the sonicator is based on the size of experiments you typically run in your lab.

How do I perform the recovery/sonication step?

You need to use a solid tray like this one: Solid Insert Tray for 3510, VWR Catalogue #100491-720.  Make sure the water bath of the ultrasonic cleaner is full of water.  Place the stainless steel tray in the water bath. Place the MBEC Assay® Kits on the stainless steel tray (don’t stack more than two plates high), then turn on the sonicator for 30 min.

How do I break the MBEC Assay® pegs off the lid for biofilm growth check or SEM analysis?

Using a flame sterile pair of needle nose pliers, grasp the base of the peg and snap the peg off by twisting the pliers. The biofilm only grows on the top third portion of the peg (the portion immersed in the inoculated media), thus there is no risk of disrupting the attached biomass.

I’m having trouble growing a biofilm. What can I do?

Here is a link to our MBEC Assay® Procedural Manual for general information for growing biofilms.
Some troubleshooting tips for growing biofilms:
– Ensure that the humidity in your incubator is 75%-90%, to avoid drying out the wells over the incubation period.
– Place your MBEC Assay® plate on the proper shaker at the proper rpm speed (110 rpm is recommended for 96 well bases)
– Start with the right inoculum concentration (105-106 CFU/mL)
– Use the proper media and growth condition for the strain you are growing (some strains require the use of a 5% CO2 incubator, or specific growth factors i.e. glucose)
– Try using the MBEC Assay® Biofilm Inoculator with 96 well base & hydroxyapatite coated pegs.  Using hydroxyapatite coated pegs typically results in greater biofilm growth, compared to the standard uncoated pegs.

If you would like more specific information or additional help, please email info@innovotech.ca with detailed information about the strain(s) and conditions you are using.

What methods of payment do you accept?

We accept wire transfers, credit card via PayPal, purchase orders and cheques.

My package is delayed in customs. What should I do?

Customs delays typically occur for two reasons: either border agents require additional information about the shipment or customs fees are required to be paid.
Call your country’s courier information center with your tracking number to assess the situation. If you need assistance, please email info@innovotech.ca.
