Western Blot: GPR81 Antibody - BSA Free [NLS2095] - Stable knockdown of GPR81 in MDA-MB-231 cells. Using a lentiviral system, GPR81 was stably knocked down in MDA-MB-231 cells with GPR81-specific short hairpin RNA (shGPR81 #1) & compared with cells containing scrambled shRNA as a control (shNT). Knockdown of GPR81 was confirmed by (a) western blotting & (b) RT-qPCR. The GPR81, MCT1, & MCT4 mRNA levels in the shGPR81 #1 cells are presented as the fold increase compared with those in shNT cells. Data are presented as the means ± s.d. (n = 3/group). **p < 0.01; Student’s t-test. (c) Lactate production in shNT & shGPR81 #1 cells. The cells were cultured for 24 h & lactate concentrations in the supernatants were determined (n = 3/group). **p < 0.01 (vs. shNT cells); Student’s t-test.

Immunohistochemistry Protocol for GPR81 Antibody (NLS2095):
Immunohistochemistry

1. Prepare tissue with formalin fixation and by embedding it in paraffin wax.
2. Make 4 um sections and place on pre-cleaned and charged microscope slides.
3. Heat in a tissue-drying oven for 45 minutes @ 60 degrees Celcius.
4. Deparaffinize the tissues by wash drying the slides in 3 changes of xylene for 5 minutes each @ RT.
5. Rehydrate the tissues by washing the slides in 3 changes of 100% alcohol for 3 minutes each @ RT.
6. Wash the slides in 2 changes of 95% alcohol for 3 minutes each @ RT.
7. Wash the slides in 1 change of 80% alcohol for 3 minutes @ RT.
8. Rinse the slides in gentle running distilled water for 5 minutes @ RT.
9. Perform antigen retrieval by steaming the slides in 0.01M sodium citrate buffer (pH 6.0) @ 99-100 degrees Celcius
for 20 minutes.
10. Remove the slides from the heat and let stand in buffer @ RT for 20 minutes.
11. Rinse the slides in 1X TBS-T for 1 minute @ RT.

**Do not allow the tissues to dry at any time during the staining procedure**

12. Begin the immunostaining by applying a universal protein block for 20 minutes @ RT.
13. Drain protein block from the slides and apply the diluted primary antibody for 45 minutes @ RT.
14. Rinse the slide in 1X TBS-T for 1 minute @ RT.
15. Apply a biotinylated anti-rabbit IgG (H+L) secondary for 30 minutes @ RT.
16. Rinse the slide in 1X TBS-T for 1 minute @ RT.
17. Apply an alkaline phosphatase steptavidin for 30 minutes @ RT.
18. Rinse the slide in 1X TBS-T for 1 minute @ RT.
19. Apply an alkaline phosphatase chromagen substrate for 30 minutes @ RT.
20. Rinse the slide in distilled water for 1 minute @ RT.

**This method should only be used if the chromagen substrate is alcohol insoluble (ie: Vector Red, DAB)**

21. Dehydrate the tissue by washing the slides in 2 changes of 80% alcohol for 1 minute each @ RT.
22. Wash the slides in 2 changes of 95% alcohol for 1 minute each @ RT.
23. Wash the slides in 3 changes of 100% alcohol for 1 minute each @ RT.
24. Wash the slides in 3 changes of xylene for 1 minute each @ RT.
25. Apply cover slip.
