ioGlutamatergic Neurons^™

Human iPSC-derived glutamatergic neurons

ioGlutamatergic Neurons have been precision reprogrammed from human induced pluripotent stem cells (iPSC) using opti-ox™ technology. Within days, cells convert consistently to mature, functional glutamatergic neurons characterised by  >80% expression of glutamate transporter genes VGLUT1 and VGLUT2.

Glutamatergic neurons are delivered cryopreserved and ready-to-culture making them a high-quality human model for fundamental research, disease modelling and drug discovery.

Benchtop benefits

Quick

Ready for experimentation as early as 2 days post revival and form functional neuronal networks at 17 days.

Scalable

Industrial scale quantities at a price point that allows the cells to be used from research to screening scale.

Easy to use

Cells arrive programmed to rapidly mature upon revival. One medium is required in a two-step protocol.

Rapid gain of functional activity

ioGlutamatergic Neurons display neuronal activity that matures over-time

Examples of MaxOne high-resolution multi electrode array (MEA) recordings of ioGlutamatergic Neurons in BrainPhys™ media. The activity maps show firing rate (A), spike amplitude (B) and % of active electrodes (C). Results demonstrate a time-dependent increase of spontaneous activity during neuronal maturation from 2 to 3 weeks post-revival.

(C) An example of a bursting phenotype, taken at day 20 post-revival (1 second sweep, 16 µV/-16 µV). Cells were cultured in the bit.bio recommended open-source medium and recorded on 64-electrode MEAs.

Array Wide Spike Detection Rate histograms (AWSDR – a graphical measure of synchrony) for 10-minute recordings on day 8, 13 and 20 post-revival ioGlutamatergic Neurons in co-culture with primary rat-derived astrocytes. Results show prominent synchronicity on day 13, exemplified by the ‘spikier’ nature of the associated AWSDR, which increases at day 20. Cells were cultured in the bit.bio recommended open-source medium and recorded on 64-electrode MEAs.

Robust and scalable cells for high-throughput screening

ioGlutamatergic Neurons show good suitability for high-throughput screening in 384-well format plates

Cytotoxicity CellTiter-Glo®️ (CTG) and TR-FRET (HTRF®️) assays for AKT serine/threonine kinase 1 (AKT) and Huntingtin (HTT) proteins were performed on ioGlutamatergic Neurons in 384-well plates treated with tool compound (cmp) at day 9 post-revival. Compound titration results in a concentration response curve for all three assays (mean±sd of 2 replicates). CTG assay on ioGlutamatergic Neurons shows an excellent average signal/ background ratio and high suitability for HTS. HTRF® assays on ioGlutamatergic Neurons show lower signals but with low variability, and could therefore also provide a suitable platform for HTS.

Industry leading seeding density

Do more with every vial

The seeding density of our human iPSC-derived glutamatergic neurons has been optimised and validated making it possible to have a cost point of under £0.67 (~$0.79) per well (96 well plate, seeding density 30,000 cells/cm², Large vial size).

This means scientists are able to do more with every vial and expand experimental design within budget without losing out on quality. Resulting in more experimental conditions, more repeats, and more confidence in the data.

One Small vial can plate a minimum of 0.7 x 24-well plate, 1 x 96-well plate, or 1.5 x 384-well plate.

One Large vial can plate a minimum of 3.6 x 24-well plate, 5.4 x 96-well plate, or 7.75 x 384-well plates.

Easy culturing

Cells arrive ready to plate

ioGlutamatergic Neurons are delivered in a cryopreserved format and are programmed to rapidly mature upon revival in the recommended media. The protocol for the generation of these cells is a three-phase process: 1. Induction (carried out at bit.bio) 2. Stabilisation for 4 days 3. Maintenance during which the neurons mature.
