Mice were genotyped at JAX: the presence of the floxed gene was demonstrated by PCR, with flox-F ACC CAT GTG GAA AGA AA and flox-R TGC AGG CAC TAA AGA CGA TG primers producing a 505 bp amplicon.9 (link) For evaluation of cre recombination, the flox-F primer was paired with excision-R primer CAG AAA GAA CTA CAC AGA GAA ATC; excision results in a 520 bp amplicon. Mice with desired genotype from JAX were shipped for analysis. Genomic DNA was isolated from fresh lysates of whole marrow and spleen cells for PCR genotyping using REDExtract-N-Amp tissue PCR kit (Sigma, St. Louis, MO). To confirm Orai1 deletion from myeloid monocytic cells, spleens were gently dissociated in PBS pH 7.2, 0.5% BSA, and 2 mM EDTA. Cells were incubated with anti-F4/80-linked magnetic micro-beads and separated by AutoMACS (Miltenyi Biotech, Bergisch Gladbach, Germany). Aliquots of unsorted spleen cells were also frozen for Western blot analysis (see below). Genomic DNA for PCR was extracted from F4/80-positive and negative cells (Sigma REDExtract-N-Amp tissue PCR kit). Amplification used 94°C, 4 minutes, 30 cycles of 94°C, 30 seconds, 58°C, 30 seconds, and 72°C, 30 seconds and final extension 72°C, 2 minutes. Products were separated on 1.5% agarose.

DNA extraction from mouse tail clips obtained at 7–10 days of age was performed using REDExtract-N-Amp™ Tissue PCR Kit (Cat#R4775, Sigma-Aldrich, St. Louis, MO, USA) following the manufacturer’s protocol. In brief, tail clips were combined with 100 μL of extraction solution and 25 μL of tissue preparation solution and mixed by vortexing. Samples were incubated for 15 min at room temperature followed by incubation at 95 °C for 5 min. A total of 100 μL of neutralization solution was added to each sample and again mixed by vortexing.
The extracted DNA was subsequently used to perform genotyping PCR. The primers of interest were combined with the extracted DNA, double-distilled water, and REDExtract-N-Amp™ PCR Ready Mix (Cat#R4775, Sigma-Aldrich, St. Louis, MO, USA) to obtain a total volume of 20 μL per reaction. PCR was performed using an Applied Biosystems Thermal Cycler; individual thermal protocols were primer-specific (Supplementary Table S1). A total of 2.5–8 μL of the final samples were run out on 1.5% agarose gels for BAP1 and Kras specimens and 3% agarose gels for Alb-Cre specimens. Primer sequences and expected amplicon sizes are found in Supplementary Figure S1.

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.
