• Plate 0.25x10⁶cells/ml in 2ml/well of cells in a 6 well plate.
• Grow cells for 24h at 37°C and 5% CO₂.
• Transfect cells with 2ug/well of a plasmid expressing human GRM6 under the control of the ubiquitous promoter CMV using TransIt-LT1 transfection reagent (Mirus, Mir2300, lot 81104333) following the manufacturer´s instructions.
• Grow cells for 72h at 37°C and 5% CO₂.
• Harvest cells with PBS and lyse them on ice for 30min with 50µl/well of RIPA buffer (25mM TrispH7-8, 150mM NaCl, 0.1% SDS, 0.5% sodium deoxycholate, 1% Triton X-100 or NP-40).
• Complete the lysis with a freeze/taw cycle.
• Determine total protein content of the lysates using Pierce BCA protein assay (Thermo Fisher, 23221).
• Denature 25μg of total protein for 20min at 37°C in 20μl Laemmli SDS sample buffer and subsequently separate them on a denaturing 4-20% Mini-PROTEAN TGX Stain-Free Gel (Bio-Rad, 456-8094) for 20min at 100V and 2h at 130V.
• Transfer proteins onto Immobilion-P transfer membrane (Immobilion, IPVH00010) for 75min at 100mA.
• Block the membrane with TBST 5% milk for 1h at RT.
• Incubate with primary
• • rabbit anti-GRM6 antibody (antibodies-online, ABIN1533291, lot 310210) diluted 1:1000 in TBST 5% milk ON at 4°C,
  • rabbit anti-GRM6 antibody (antibodies-online, ABIN2704985, lot 73482) diluted 1:1000 (positive control), or
  • mouse anti-GAPDH antibody (Fitzgerald, 10R-G09a, lot 2417) diluted 1:40000 in TBST 5% milk ON at 4°C.
• Wash membrane 3x for 5min with TBST buffer.
• Incubation with secondary
• • HRP conjugated goat anti-rabbit antibody (Jackson Immuno Research, 111-035-144) diluted 1:3000 in TBST 5% milk for 45min at RT or
  • goat anti-mouse antibodies (Jackson Immuno Research, 115-035-146) diluted 1:3000 in TBST 5% milk for 45min at RT.
• Wash membrane 3x for 10min with TBST buffer.
• Reveal protein bands using Clarity MAX Western ECL Substrate (Bio-Rad, 1705062) on a ChemiDoc MP imaging system (Bio-Rad, 17001402).

Notes:

• ABIN1533291 reveals two distinct bands. A lower one, which molecular weight corresponds to the monomer of the target protein, and a higher one which appears to correspond to a dimer of GRM6. The protein bands are only visible in the positive but not in the negative controls. Importantly, the same result was observed with another anti GRM6 antibody (ABIN2704985).

• Being a G-Protein-Coupled Receptor it is not surprising that GRM6 forms strong dimers that can withstand boiling. Several attempts were performed in order to dissolve such dimers including sonication and different boiling protocols but they were unsuccessful. Similar results were obtained with HEK293 cells as well (not shown).

Independent Validation (IF)

Validation #103795 (Immunofluorescence)

by: Group Kleinlogel, Department of Physiology, University of Bern, Bern, Switzerland

No.: #103795

Date: 15.03.2019

Antigène: GRM6

Numéro du lot: 310210

Application validée: Immunofluorescence

Contrôle positif:

Chinese Hamster Ovary (CHO-K1) cells transfected with a plasmid expressing human GRM6 and turbo Red Fluorescent protein (tRFP)

Contrôle négative:

Non-transfected CHO-K1 cells

CHO transfected with a plasmid expressing human GRM6 stained with secondary antibody only

Conclusion:

Passed. ABIN1533291 specifically labels the targeted antigen in transfected CHO-K1 cells in IF as demonstrated by the co-labeling with tRFP. No specific signal was detected in the negative controls.

Validation Images

Low and high magnification pictures of CHO-K1 cells, transfected with a plasmid expressing human GRM6 and turbo Red Fluorescent protein (tRFP) stained with ABIN1533291 and an AF488 conjugated secondary antibody (AF488). Co-labeling of tRFP and GRM6 indicates the specificity of the antibody. Non-transfected cells (non-transfected) and transfected cells stained with the secondary antibody only (secondary) served as negative controls.
