Rag1 knockout mice

Manufactured by Jackson ImmunoResearch
Sourced in United States

Rag1 knockout mice are genetically modified mice that lack the recombination-activating gene 1 (Rag1). This gene plays a crucial role in the development of T and B cells, which are essential components of the adaptive immune system. Rag1 knockout mice are commonly used as a model system in immunological research to study the function and development of the immune system.

T Cell-Specific DOT1L Deletion in Mice

Check if the same lab product or an alternative is used in the 5 most similar protocols
Six- to eight-week-old female wild-type C57BL/6, BALB/c, and Rag1 knock out (KO) mice were from the Jackson Laboratory (Bar Harbor, ME, USA). Dot1lflox/flox mice were bred with CD4-Cre mice to generate mice with specific DOT1L deletion in T cells. All mice Dot1lf/f or Dot1l−/− mice were utilized at the age of 6–12 weeks unless specified in the text. Mice were housed under specific pathogen-free conditions and handled according to the guidelines of the University Committee on the Use and Care of Animals at the University of Michigan.

Evaluating Anti-PD-1 Immunotherapy in Mice

Check if the same lab product or an alternative is used in the 5 most similar protocols
All animal experiments were approved by the Institutional Animal Care and Use Committee (IACUC) of University of California, San Diego (UCSD). Wild type (WT) C57BL/6 were purchased from Jackson Laboratories. Rag-1 knockout mice were obtained from Jackson Laboratories and bred by the UCSD Animal Care Program. The TLR7 agonist, 1V270, was synthesized by our laboratory [23 (link)]. Rat anti–mouse PD-1 (clone J43, BE0033–2), rat anti-mouse CD8 (Clone YTS169.4, BE0117) and rat anti-mouse CD4 (Clone GK1.5, BE0003) monoclonal antibodies were purchased from BioXcell.

Generation of Batf Conditional Knockout Mice

Check if the same lab product or an alternative is used in the 5 most similar protocols
Batffl/fl mice were kindly provided by E.J. Taparowsky (Betz et al., 2010 (link)). PLZF-Cre recombinase mice (stock #:024529) were purchased from the Jackson Laboratory and crossed to one another to generate age-matched Batffl/flPLZF-Cre (WT) and Batffl/flPLZF-Cre+ (Batf innate lymphoid cell-conditional knockout, cKO) mice. Batf knockout mice (stock #: 013758) and Rag1 knockout mice (stock #:129S7) were purchased from Jackson Laboratory. Rag1−/−Batf−/− mice were generated by crossing Rag1−/− with Batf−/− mice. R26-CreERT2 mice (stock #: 008463) and RosamT/mG reporter mice (stock #: 007576) were purchased from the Jackson laboratory. Batffl/fl was crossed with ERT2CreRosamTmG to generate Batffl/flERT2CreRosamTmG mice. Mice were bred and maintained in a closed breeding facility, and mouse handling conformed to the requirements of the Institutional Animal Care and Use Guidelines of the Medical College of Wisconsin.

Generation of CD11c-specific SOCS1 knockout mice

Check if the same lab product or an alternative is used in the 5 most similar protocols
To generate mice in which SOCS1 was specifically deleted in CD11c+ cells, CD11c-Cre-GFP transgenic mice (19 (link)) were obtained from The Jackson Laboratory (Stock#007567, Bar Harbor, ME) and bred with SOCS1fl/fl mice (15 (link)) (generously provided by Dr. Yoshimura, Keio University). Five to ten week old sex-matched Cre-SOCS1f/f and CD11c-Cre+ SOCS1f/f littermates were used for all experiments. C57BL/6 mice, OT-1 mice bearing a TCR specific for the SIINFEKL epitope of ovalbumin on a Rag1-/- background, and Rag1-/- knockout mice were purchased from The Jackson Laboratory (Bar Harbor, ME). Animal protocols were approved by the Earle A. Chiles Research Institute IACUC (Animal Welfare Assurance No. A3913-01).

Behavioral and Biochemical Analyses of Mice

Check if the same lab product or an alternative is used in the 5 most similar protocols
Adult C57BL/6J mice (males and females, 8-10 weeks) were used for all behavioral and biochemical studies. STING "goldenticket" knockout mice (Stock No: 017537), Ifnar1 global knockout mice (Stock No: 028288), Rag1 knockout mice (Stock No: 002216), Ifnar1 conditional knockout mice (Ifnar1 fx/fx ; Stock No: 028256) and Batf3 -/-mice (Stock No: 013755) were purchased from the Jackson Laboratory and maintained on a C57BL/6J background. Nav1.8-Cre mice, also maintained on a C57BL/6J background, were a gift from Rohini Kuner (University of Heidelberg). Behavioral testing was performed comparing STING gt/gt and Ifnar1 -/-mice with wildtype littermate controls. These mice were maintained at an AAALAC-approved Duke University facility with two to five mice housed in each cage maintained in a 12h light-dark cycle with ad libitum access to food and water. Animals were randomly assigned to different experimental groups. Our previous studies using similar types of behavioral and biochemical analyses 27, (link)45, (link)46 (link)

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.
