This antibody was used in a study investigating the effects of N-glycosylation of Matrix Metalloproteinase-9 (MMP9) by characterizing the intracellular organelle trafficking pattern of MMP9 N-glycoyslation mutants. It has been published in Traffic in 2015 (Duellman et al., Functional Roles of N-Linked Glycosylation of Human Matrix Metalloproteinase 9, Traffic. 10, 1108-26). Anti-Golgin 97 was used to characterize the staining pattern of the Golgi Apparatus and compared to a GFP molecular construct engineered to localize within the Golgi Apparatus. Anti-Golgin 97 stained the 4% PFA fixed HEK293 cells and resulted in a weak but distinguishable signal and appeared in a similar detection pattern as our Golgi-localizing GFP construct. A dilution of 1:100 incubated for 3 hours was used followed by secondary staining using Alexa-488.

Experimental Design and Results Summary

Applications

Immunofluorescence

Sample

4% PFA fixed HEK293 cells were used to detect the Golgi Apparatus staining pattern using Anti-Golgin 97. Green signal is the immunodetection of Anti-Golgin 97, blue signal is Hoechst stain.

Primary Incubation

A dilution of 1:100 in 2% DGS was incubated at room temperature for 3 hours.

Blocking Agent

10% Donor Goat Serum (DGS)

Secondary Incubation

A dilution of 1:400 of anti-Rabbit-488 (Alexa series) in 2% DGS was incubated at room temperature for 1 hour.

Tertiary Incubation

N/A

Detection

488nm excitation on an inverted microscope.

Results Summary

The Anti-Golgin 97 antibody resulted in a typical staining pattern that resembled the Golgi Apparatus and mimiked the patterning of our eGFP miolecular construct which was engineered to localize to the Golgi Appartus upon expression in HEK293 cells.

Summary

The Good

Staining pattern was able to successfully detect the Golgi Apparatus in HEK293 cells.

The Bad

The signal was relatively weak.

The Bottom Line

The antibody worked well enough. I would recommend use at a higher concentration and potentially use tyramide enhancement if necessary.
