Ot 2 tcr transgenic mice

Manufactured by Jackson ImmunoResearch
Sourced in United States

OT-II TCR transgenic mice express a T cell receptor (TCR) specific for the ovalbumin (OVA) peptide presented by the MHC class II molecule I-A^b. These mice are a useful tool for the study of CD4+ T cell responses in the context of antigen presentation and immune system activation.

CD11c+ cell specific gp96-deficient mice (CD11cCre+Hsp90b1flox/flox) and control littermates (CD11cCreHsp90b1flox/flox) were generated by crossing our Hsp90b1flox/flox (gp96 is encoded by Hsp90b1) mice36 (link) with CD11c-cre transgenic mice59 (link). These gp96-deficient mice were further crossed with CX3CR1-GFP transgenic mice46 (link) (Jackson laboratory) to define CX3CR1+ population. OT-II TCR transgenic mice were purchased from Jackson laboratory and bred onto the Ly5.1 background. All animal experimental protocols were approved by the Medical University of South Carolina Institutional Animal Care and Use Committee (IACUC).

Eight- to 16-week-old male and female mice were used for experiments; sexes are recorded in each figure legend. Animals were housed in the Dean McGee Eye Institute's specific-pathogen-free vivarium for at least 1 week prior to experimentation. Wild-type (WT) C57BL/6 and OT-II TCR transgenic mice were obtained from the Jackson Laboratory (Bar Harbor, ME, USA). Transgenic C57BL/6-background alpha smooth muscle actin GFP-reporter mice (α-SMA-GFP)32 (link) were bred in-house. Transgenic C57BL/6-background mice expressing a floxed vascular endothelial growth factor A allele (Vegfaflox)33 (link),34 (link) were bred within our institution's Rodent Barrier Facility and were originally provided by Genentech (South San Francisco, CA, USA). Mice were anesthetized by intraperitoneal (IP) injection with xylazine (6.6 mg/kg) and ketamine (100 mg/kg) for all procedures and euthanized by exsanguination via intracardiac perfusion with 10 mL PBS prior to tissue collection. The Institutional Animal Care and Use Committee at the University of Oklahoma Health Sciences Center approved all procedures. Experiments were conducted in accordance with the ARVO Statement for the Use of Animals in Ophthalmic and Vision Research.

Generation of FLIP-deficient CD11c+ Mice

Check if the same lab product or an alternative is used in the 5 most similar protocols
We generated a mouse line with FLIP deficient in CD11c+ cells (CD11c-Flip-KO), aka HUPO mice on a C57BL/6 background, genotyped as Flipflox/floxCD11ccre. HUPO mice are generated by crossing Flipflox/flox mice with CD11c-Cre-GFP transgenic mice (CD11c-Cre-GFP line 4097, Jackson stock 007567).26 (link),27 (link) Control mice were littermates or age and gender matched mice without Flip genomic deletions, genotyping as Flipflox/+CD11ccre or Flipflox/floxCD11c+. We generated HUPO-Rag-/- mice line by crossing HUPO with Rag-/- mice (RAG2 KO, Jackson stock 008449). The HUPO or control mice on C57BL/6 CD45.1+ background were generated by crossing with CD45.1 congenic strain (B6 CD45.1, Jackson stock 002014). OTII TCR-transgenic mice are from Jackson Laboratory (OTII, Jackson stock 004194). All mice were confirmed by PCR genotyping employing genomic DNA extracted from tail biopsies. Also, the CD45.1 or CD45.2 backgrounds were determined by blood flow cytometry employing antibodies to CD45.1 or CD45.2. All mice were breed on the C57Bl/6 background. All mice were bred and maintained in Northwestern University barrier animal facility and all procedures followed ethical guidelines and approved by Northwestern IACUC.

Senp7-floxed mice were generated at the GemPharmatech using a LoxP-targeting system. The Senp7-floxed mice were crossed with Cd4-Cre transgenic mice (The Jackson Laboratory) to produce age-matched Senp7fl/fl and Senp7fl/flCd4-Cre mice. The Pten-floxed mice (The Jackson Laboratory) were crossed with Senp7fl/flCd4-Cre mice to produce Senp7+/+Ptenfl/flCd4-Cre (Pten-KO) and Senp7fl/flPtenfl/flCd4-Cre (DKO) mice. Rag1-KO mice, OT-I TCR–transgenic mice, OT-II TCR–transgenic mice, and B6.SJL mice were from The Jackson Laboratory. Male and female mice were sex matched and used at 6 to 10 weeks of age.

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.
