Xenogen ivis

Manufactured by PerkinElmer
Sourced in United States

The Xenogen IVIS is a non-invasive in vivo imaging system designed for real-time monitoring and quantification of bioluminescent and fluorescent reporters in small animal models. The system utilizes a highly sensitive charge-coupled device (CCD) camera to capture high-resolution images of luminescent or fluorescent signals within living animals.

Check if the same lab product or an alternative is used in the 5 most similar protocols
T24 bladder cancer cells stably expressing luciferase (1 × 105) were suspended in 200 μL PBS and injected into the lateral tail veins of 5-week-old male B-NDG mice (BIOCYTOGEN, Beijing, China). Four weeks later, mice were anaesthetized with isoflurane, and D-luciferin sodium salt (150 mg/kg) was injected intraperitoneally. Bladder cancer cells were detected with an in vivo imaging system, Xenogen IVIS (PerkinElmer, MA, USA). The total flux in photons per second was calculated for the lung region using Living Image 4.3.1 (PerkinElmer/Caliper).

All animal procedures were performed in accordance with Cleveland Clinic IACUC approved protocols. For in vivo limiting dilution studies, acutely dissociated GBM xenografts were sorted as TfR high (top 20%) and TfR low (bottom 20%) and recovered for 1 h in a 37°C incubator. Three dilutions (10,000, 1000, or 100 cells; n = 5 mice per group) were intracranially injected into mice 4–6 weeks of age. Brains were removed at the onset of neurological signs. For ferritin shRNA studies, luciferase-labeled CSCs were transduced with lentiviral vectors expressing NT, FTH1, or FTL shRNA. At 2 d post-transduction 10,000 viable cells were intracranially injected into mice as previously described (Flavahan et al., 2013 (link); Yan et al., 2014 (link)). A Xenogen IVIS (Perkin Elmer) was used for in vivo imaging.

Lung cancer models of NSCLC were created by injecting 5 × 106 A549-luciferase cells in sterile PBS into the tail veins of female SCID beige mice. Cancer development and progression were monitored using the Xenogen IVIS (PerkinElmer) bioluminescence imaging system. 100 μL of 30 mg/mL Xenolight Rediject D-Luciferin (PerkinElmer) was injected intraperitoneally into the mice approximately 10 min before the animals were imaged.

Mouse BCR-ABL+Arf−/−Luciferase+ B-ALL cells were injected (2×105) into non-conditioned, 6–8 week-old, female C57BL/6 recipients (Jackson Laboratory). Five days after the transfer, recipients were treated with DHA and ABT-263 by oral gavage. ABT-263 was formulated in a mixture of 60% Phosal 50 PG, 30% PEG 400, and 10% EtOH and dosed at 100 mg/kg/day as previously described (28 (link)). DHA was formulated in 0.5% carboxymethylcellulose, 0.5% Tween-80, and 0.5% benzyl alcohol and dosed at 200 mg/kg/day. Treatment was given daily for 15 days (days 5–20) during and after which the mice were monitored. Mice were bred and utilized in accordance with SJCRHACUC. Bioluminescence imaging was assessed by Xenogen IVIS (Perkin Elmer, MA) after mice were injected with D-luciferin (Perkin Elmer) at 150 mg/kg. Images (photons/second) were quantified through application of a contour drawn around the target region and normalized to maximum luminescence activity. For ex vivo analysis of MCL-1 expression, recipient mice 10 days after transplant of 2×105 mouse BCR-ABL+ B-ALL cells were treated with vehicle or DHA (200 mg/kg) by gavage. Four or 8 hours after treatment, splenic blast cells were isolated and subjected to immunoblotting.

T24 bladder cancer cells stably expressing luciferase (1 × 105 cells) were suspended in 200 μL of phosphate-buffered saline and injected into the lateral tail vein of 5-week-old male B-NDG mice (Biocytogen, Beijing, China). Four weeks later, the mice were anaesthetized with isoflurane, and D-luciferin sodium salt (150 mg/kg) was injected intraperitoneally. Bladder cancer cells were counted with an in vivo imaging system, Xenogen IVIS (PerkinElmer, Boston, MA, USA). The total flux of photons per second was calculated for the lung region using Living Image 4.3.1 software (PerkinElmer/Caliper).

All animal experiments were approved by the Institutional Animal Care and Use Committee (IACUC) of Peking University First Hospital (Beijing, China) and conducted in accordance with its recommendations and ethical regulations. For the tumour xenograft implantation experiment, 1 × 105 SW780 cells were injected subcutaneously into 5-week-old male BALB/c nude mice (Vital River, Beijing, China), which were subsequently sacrificed 8 weeks later. For the metastasis experiment, 1 × 105 5637-Luc cells were suspended in 200 μL PBS and injected into the lateral tail veins of 5-week-old male B-NDG mice (BIOCYTOGEN, Beijing, China). Four weeks after the injection, mice were anaesthetized with isoflurane (YIPIN Pharmaceutical CO., LTD., Hebei, China). Ten minutes after D-luciferin was injected, sodium salt (150 mg/kg) was injected intraperitoneally, and cancer cells were detected with an in vivo imaging system, Xenogen IVIS (PerkinElmer, MA, USA). The total flux in photons per second was calculated and reported for each mouse’s lung and liver region using Living Image 4.3.1 (PerkinElmer/Caliper).

Five million 786-O cells expressing KLF5 or control vector were subcutaneously injected into 6-week-old female BALB/c nude mice (n=4 for each group). Tumor was measured weekly and volume was calculated according to the following formula: volume= length × width × (width/2). At week 11, mice were euthanized and applied to further histological analysis. For lung metastasis assay, KLF5 or vector expressed 786-O cells were infected with GFP-Luc, then three million cells were injected into retro-orbital venous plexus of nude mice (n=6 for each group). For bioluminescence imaging (BLI), D-luciferin (YEASEN, Shanghai, China) was injected into anesthetized mice and bioluminescence images were captured (Xenogen IVIS, PerkinElmer, Waltham, MA, USA). At week 12, mice were euthanized and applied to further histological analysis. All measurements were performed blindly and all animals were manipulated and housed according to protocols approved by Shanghai Medical Experimental Animal Care Commission.

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.
