AimGel Mouse T Cell Activator
Mouse T cell activation on cell-sized hydrogel microparticles


AimGel Mouse T Cell Activator
$150.00
ATC01-0050M | Research Use Only
AimGel Mouse T Cell Activator presents anti-CD3 and anti-CD28 signals on soft hydrogel microparticles built to the size of a real mouse T cell (7-12 µm). The fluid lipid membrane lets those signals move freely across the surface, the way they do on a natural antigen-presenting cell. Activation is gentle and effective, whether you start from isolated mouse T cells or straight from PBMC.
1 vial, 0.5 mL in PBS at 4 × 10⁷ microparticles/mLQuantityComing soonAimGel biomimicry
Mouse T cells clustering around AimGel microparticles decorated with anti-CD3 and anti-CD28 signals.
Our mouse T cell activator is built on our AimGel artificial cell technology, mimicking the immunological synapse for better performance: 47-fold expansion straight from PBMC, reaching ~98% CD3+ purity by day 5.

Data

Start with mouse PBMC
Expansion of mouse PBMC with AimGel Mouse T Cell Activator from PBMC, reaching 47-fold expansion by day 7.

Viability, purity and activation
Mouse T cells activated with AimGel, starting from mouse PBMC. Left: cell viability remained between 80% and 92% across days 3, 5 and 7. Centre: CD3+ fraction of live cells rose from ~14% at day 0 to ~98% by day 5, showing selective expansion of T cells without a separate isolation step. Right: ~98% of the CD3+ population was CD25+ at day 5, confirming activation.

What about second stimulation?
Thanks to gentle and biomimetic signal presentation, AimGel for mouse T cells is able to effectively restimulate the expansion of mouse T cells. Mouse PBMC were initially stimulated with AimGel for mouse T cells, and were then restimulated with AimGel for mouse T cells on day 11, except for the negative control.
FAQs
Can I start from mouse PBMC, or do I need isolated T cells?
Either. AimGel selectively expands CD3+ T cells: starting from mouse PBMC at ~14% CD3+, the population reaches ~98% CD3+ by day 5, so a separate isolation step is often unnecessary. See the protocol for seeding guidance for each starting material.
How do I remove the AimGel microparticles?
Add the included lysis buffer. Dextranase fully degrades the microparticles in 30 minutes at 37 °C, without affecting your cells. See the protocol for timings.
If you need AimGel that clears on its own at a set point, we can formulate it to hydrolyse under your culture conditions, get in touch.
Can I re-stimulate my mouse T cells?
Yes. Growth typically slows after day 10, and re-stimulating promotes continued expansion with minimal activation-induced exhaustion. We recommend an AimGel-to-cell ratio of 0.25:1 for re-stimulation.
Do not use the lysis buffer if you plan to re-stimulate, as residual dextranase will degrade freshly added AimGel unless it is thoroughly washed out.
Do I need feeder cells?
No. AimGel is a fully synthetic, feeder-free alternative with no animal components.
