Hesc qualified matrigel
HESC-qualified Matrigel is a soluble basement membrane extract of proteins derived from Engelbreth-Holm-Swarm (EHS) mouse sarcoma cells. It is used as a substrate for the in vitro culture of human embryonic stem cells (hESCs) and other cell types.

Efficient hiPSC Transfection via Lipofectamine
Cells were transfected with a complex formed with the Cas9 plasmid (VB190801_1165nbd) and two sgRNA plasmids (VB190801-1166xkk and VB190801-1168fdu), constructed by VectorBuilder, using Lipofectamine Stem transfection reagent (Invitrogen, CAT #STEM00001).
The detailed steps were as follows:
Steps | Tube | Component | Per well of a 6-well plate |
---|---|---|---|
1 | 1 | Opti-MEM™ I Medium | 100 µl |
Lipofectamine™ Stem Reagent | 4 µl | ||
2 | 2 | Opti-MEM™ I Medium | 100 µl |
DNA | 2 µg* | ||
3 | Add diluted DNA to diluted Lipofectamine Stem Reagent | ||
4 | Incubate for 10 min at room temperature | ||
5 | Add DNA-lipid complex to cells (200 µl/per well) | ||
6 | Incubate and monitor the transfected stem cells at 37 °C for 2 days |
*Equimolar amounts of Cas9 plasmid DNA and gRNA plasmid DNA were added

Differentiation of FMRP-WT and FMRP-KO hiPSCs into Cortical Neurons
hiPSCs were differentiated into cortical neurons according to a previously published protocol [37] with minor modifications. Briefly, hiPSCs were treated with Accutase (Thermo Fisher Scientific
Feeder-free Expansion of Human iPSCs
For the glass controls in the experiments -sterile rh-Vitronectin (Gibco, Life Technologies, A14700) was used to coat glass cover slips. In case of all experiments, cells were dissociated into a single cell suspension using StemPro™ Accutase™ (Gibco A1110501) cell dissociation reagent to facilitate cell counting. In case of single cell dissociation, cells were always seeded with 10uM Rock inhibitor Y27632 (ATCC® ACS-3030™).
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
