Bioluminescent Imaging of CCSP-Expressing Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
LUC;CCSP.CRE mice, bioluminescent reporters of CCSP-labeled cell mass, received one intraperitoneal injection of saline (100 μL saline) or urethane (1 g/Kg in 100 μL saline) and were serially imaged before treatment start, and at 150 and 210 days into treatment. Imaging was done on a Xenogen Lumina II (Perkin-Elmer, Waltham, MA) 5–20 min after delivery of 1 mg D-Luciferin sodium in 100 μL of sterile water to the retro-orbital vein, and data were analyzed using Living Image v.4.2 (Perkin-Elmer, Waltham, MA) (Stathopoulos et al., 2007 (link); Vreka et al., 2018 (link)).

Living cells and mice were imaged 0, 4, 8, 24, and 48 h after cellular treatments and 0 h, 4 h, and 12–14 days after pleural delivery of pNGL-expressing cells on a Xenogen Lumina II (Perkin-Elmer, Waltham, MA) after addition of 300 μg/mL D-luciferin to culture media or isoflurane anesthesia and delivery of 1 mg intravenous D-luciferin to the retro-orbital veins8 (link)–11 (link),16 (link),25 (link),34 (link),35 (link). Data were analyzed using Living Image v.4.2 (Perkin-Elmer).

In Vivo and In Vitro NF-κB Bioluminescence

Check if the same lab product or an alternative is used in the 5 most similar protocols
Mice were imaged for NF-κB reporter bioluminescent signal daily starting at day 10 post-tumor cell injection until sacrifice. For this, mice were anesthetized by isoflurane inhalation and were imaged for bioluminescence on a Xenogen Lumina II (PerkinElmer, Waltham, MA, USA) 5–20 min after delivery of 1 mg D-Luciferin potassium salt diluted in 100 μL of sterile water into a retro-orbital vein. Pleural tumors isolated from NGL mice were also imaged ex vivo for green biofluorescence using 410–440 nm background control excitation, 445–490 nm experimental excitation, and 515–575 nm emission passbands on a Xenogen Lumina II. Cells were imaged for bioluminescence on a Xenogen Lumina II 0, 4, 8, 16, and 24 h after a single addition of 300 μg/mL (equivalent to 1 mM) D-luciferin to the culture media. Data were analyzed using Living Image v.4.2 (PerkinElmer, Waltham, MA, USA) as described previously [10 (link),11 (link),20 (link),21 (link),22 (link),34 (link)].

In vivo Cre-recombinase Adenoviral Delivery

Check if the same lab product or an alternative is used in the 5 most similar protocols
Isoflurane‐anesthetized C57BL/6 and mT/mG mice received 5 × 108 PFU intrapleural or intraperitoneal Ad‐Cre or Ad‐Luc in 100 μl PBS and were serially imaged for bioluminescence on a Xenogen Lumina II (Perkin‐Elmer, Waltham, MA) after receiving 1 mg retro‐orbital D‐luciferin under isoflurane anesthesia, and data were analyzed using Living Image v.4.2 (Perkin‐Elmer; Stathopoulos et al, 2006 (link); Spella et al, 2019 (link)), or were euthanized and pleural lavage was performed, lungs were explanted, and parietal pleura was stripped. For pleural lavage, 1 ml PBS was injected, was withdrawn after 30 s, and was cytocentrifuged onto glass slides (5 × 104 cells, 300 g, 10 min) using CellSpin (Tharmac, Marburg, Germany). Lungs were embedded in optimal cutting temperature (OCT; Sakura, Tokyo, Japan) and sectioned into 10‐µm cryosections. The parietal pleura was placed apical side up onto glass slides. Samples were stained with Hoechst 55238 and were examined on AxioObserver D1 (Zeiss, Jena, Germany) or TCS SP5 (Leica, Heidelberg, Germany) microscopes.

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.
