S were removed from culture at days 0, 3, 5, and 7 for flow cytometric analysis and DNA extraction (Qiagen). On day 5 and 7, cells were split and given 15 ng/ml of IL-4 and 20 ug/ml of 10781694 LPS or LPS alone.Molecular Genotyping of Mouse StrainsFor genotyping by PCR, genomic DNA was extracted from tail tissue using Extract-N-Amp Tissue Kit (Sigma-Aldrich). All primer sequences used for genotyping are available upon request. ToHistopathologyMouse tissues were fixed in 10 neutral buffered formalin for at least 48 hours, dehydrated in an alcohol gradient, cleared inGC B-Cells Resist Transformation by Krasxylene, and infiltrated and embedded in paraffin. Sections were stained for hematoxylin/eosin (H E).Figure S3 Subtle changes in immunoglobulin isotypeFlow Cytometric AnalysisSingle cell suspensions of bone marrow and Tes immune responses in prostate cancer (data not shown). The IFN spleen briefly underwent red blood cell lysis. 1610 6 cells were pre-incubated for 3 minutes on ice with Fc block (CD16/CD32; BD Pharmingen, Franklin Lakes, New Jersey), stained for 25 min on ice with specific antibodies and washed twice in PBS/0.5 M EDTA/0.5 g BSA. The following antibodies used were obtained from BD Pharmingen, unless noted otherwise: FITC-B220 (RA3-6B2), PE-IgM (II/41; eBioscience), APC-IgG1 (X56), AlexaFluor-647 GL7 (eBioscience), PE-CD138 (281-2), PECy7-B220 (RA3-6B2), PE-CD4 (GK1.5), and FITCCD8. 16985061 Flow cytometric analysis was performed using FACScan (Becton Dickinson, Franklin Lakes, New Jersey), modified with additional lasers (Cytek Development). FlowJo software (Tree Star, Ashland, Oregon) was used to analyze a minimum of 10,000 events acquired during collection.`MoFloTwo 8-week-old Cc1-Cre KrasG12D or Kras AID-Cre mice were stimulated with 100 ug CGG intraperitoneally and sacrificed 14 days later. Preparation of spleen and bone marrow was previously described. Flow cytometric analysis was performed with the MoFlo single-cell sorter (Becton-Coulter, Brea, Ermore, perfusates exclude the influence of other organs. It should be California).responses in AID-Cre-YFP KrasG12D mice detected by enzyme linked immunosorbant assay (ELISA). A) Total serum gamma region protein levels from AID-Cre-YFP KrasG12D and control KrasG12D mice calculated from total serum protein multiplied by the percentage of protein in the gamma region of serum protein electrophoresis (SPEP) divided by 100. Results are shown from untreated AID-Cre-YFP KrasG12D vs KrasG12D mouse cohorts (immunization protocol only; left panel), AID-Cre-YFP KrasG12D vs KrasG12D cohorts fed vitamin D deficient chow (middle panel) and AID-Cre-YFP KrasG12D vs KrasG12D cohorts given radiation (right panel). B) Serum ELISA of indicated immunoglobulin isotypes of untreated KrasG12D and AID-Cre-YFP KrasG12D mice. All changes were small in magnitude, but statistically significant differences were noted at baseline in IgM, IgA and IgG3 isotypes, at 9 month IgG2b timepoint and total IgG at endpoint. Serum samples were taken at baseline, prior to immunization with NP-CGG; PPI, post-primary immunization; PBI, post-boosting immunization; 9 mo, 9 month time point; Endpt, endpoint prior to sacrifice.
