Live Dead Assay:

Article Title: Biomimetic 3D-Printed Adaptive Hydrogel Bioadhesives Featuring Superior Infection Resistance for Challenging Tissue Adhesion, Hemostasis, and Healthcare.
Article Snippet: .. For the live-dead assay, hydrogels containing cells were stained with Calcein-AM and ethidium homodimer1 (live-dead cell staining kit) for 1 h. For the cellular morphology study, hydrogels containing cells were fixed with 3.7% PFA solution for 45 min and 0.1% Triton X-100 for another 10 min; after washing with PBS, stained with 10 μg mL−1 Alexa Fluor 488 Phalloidin for 45 min and colored with 1 μg mL−1 of 4,6-diamidino-2-phenylindole (DAPI) for 10 min. Lastly, the stained cells were imaged using a fluorescence microscope (EVOS 5000 Thermo Fisher Scientific). ..

Article Title: Microfluidic device to study spatial and temporal response of astrocyte networks in response to changes in the biochemical milieu
Article Snippet: Primers for genes of interest were obtained from Thermo Fisher. .. We aspirated the media from all reservoir wells and replaced it with a 4% PFA solution (Ref: AA433689L; Thermo Fisher Scientific) and refrigerated it for 48 h. We then washed with Tween 20% (Ref: 50-176-4983, Sigma Aldrich) to remove the PFA and added Triton X-100 (Ref: 9036-19-5; Sigma Aldrich) to induce cell permeability. ..

Article Title: Loss of nephronophthisis-associated nephrocystin-1 impairs DNA damage repair in kidney organoids
Article Snippet: Additionally, the raw data were deposited in the public repository Figshare ( https://figshare.com ). .. After completing the maturation protocol, the organoids were washed 3 times with PBS and fixed with 2% PFA solution (PierceTM 16% formaldehyde (w/v), methanol-free, ThermoFisher) on ice for 20 min. After incubation, PFA was removed, and organoids were washed 3 times with PBS. ..

Immunofluorescence:

Article Title: SPTBN2 promotes an immunosuppressive tumor microenvironment and cross-resistance to anti-cancer therapies
Article Snippet: For CD8 + T-cell cytokine production analysis, 2 × 10 6 cells were treated with 2μL of activation cocktail/mL in RPMI-1640 Medium (Gibco, #22400089), supplement with 10% HyClone fetal bovine serum (Cytiva, #SH30071.03), 1mM sodium pyruvate (Gibco, #11360070),1× Antibiotic/Antimycotic Solution(Cytiva, #SV3007901), 55μM 2-mercaptoethanol (Sigma, #60242), for 4-6 hours before collection for the staining process. .. For immunofluorescence, the OCT-stored tissues were cut into 8.0 μm sections onto glass slides and fixed in a 4% PFA solution (Thermo, #J19943-K2) at room temperature for 15 minutes. ..
