Validation #029611 (Immunofluorescence)

by: CaresBio Laboratory

No.: #029611

Date: 11.02.2014

Numéro du lot: YEYY9

Application validée: Immunofluorescence

Contrôle positif: MCF7 cells

Contrôle négative: HeLa cells

Conclusion: Strong signal was detected in positive control tissues and not in negative control tissues. Note that there was a small amount of signal generated in the negative control sample.

Protocole

Anticorps primaire:

• Antigen: Low Density Lipoprotein Receptor-Related Protein 2 (LRP2) antibody (Cy3)
• Catalog number: ABIN750991
• Lot number: YEYY9

Anticorps secondaire:

• Used only for the secondary only control, as primary antibody was directly conjugated to Cy3
• Antibody: Cy3 Goat Anti-Rabbit IgG (H+L)

Full Protocol:

• MCF7 and HeLa cell lines were grown directly on coverslips and fixed with 4% formaldehyde in PBS for 15 min at room temperature (RT).
• Fixed cells were rinsed three times in PBS for 5 min each at RT.
• Cells were blocked in 1X PBS/1% BSA/0.3% Triton™ X-100 to block unspecific binding of the antibodies for 60 min at RT.
• Cells were incubated with fluorophore conjugated primary antibody diluted 1:250 and 1:100 in 1X PBS/1% BSA/0.3% Triton™ X-100 overnight at 4°C.
• Cells were rinsed three times in PBS for 5 min each at RT.
• Coverslips were mounted on slides with ProLong® Gold Antifade Reagent with DAPI.
• Isotype control staining:
• All the steps are done same as previously described until cells were blocked in 1X PBS/1% BSA/0.3% Triton™ X-100 to block unspecific binding of the antibodies for 60 min at RT. - Cells were incubated with 10% normal rabbit serum overnight at 4°C.
• Cells were rinsed three times in PBS for 5 min each at RT.
• Cells were incubated with goat anti rabbit CY3 conjugated secondary antibody for 60 min in dark at RT.
• Cells were rinsed three times in PBS for 5 min each at RT.
• Coverslips were mounted on slides with ProLong® Gold Antifade Reagent with DAPI. Secondary only staining:
• All the steps are done same as previously described until cells were blocked in 1X PBS/1% BSA/0.3% Triton™ X-100 overnight at 4°C. - Cells were incubated with goat anti rabbit CY3 conjugated secondary antibody for 60 min in dark at RT.
• Cells were rinsed three times in PBS for 5 min each at RT.
• Coverslips were mounted on slides with ProLong® Gold Antifade Reagent with DAPI.
• Stained cells were imaged with a Nikon C2+ confocal microscope.

Notes: We did the first set of experiment with 1:250 dilution of the primary antibody but have observed lower level of expression of LRP2 in MCF7 (positive) cells (Figure 2). We repeated experiment with higher concentration of the primary antibody (1:100) and the expression level increased as shown in Figure 1. We have noticed lower level of expression of LRP2 in HeLa (negative) cells (Figure 3). We have used rabbit normal serum for isotype control to match the species with primary antibody (rabbit) and also we used bovine albumin serum (BSA) as blocking and antibody diluent buffer to reduce species cross reactivity.
