Applications

The use of MA00308 in the following tested applications has been tested. The titer was measured using indirect assay with the concentration of the antibody at 1mg/ml. The application notes include recommended starting dilutions. Optimal
dilutions/concentrations should be determined by the end user. Higher dilution than suggested maybe used in IHC and IF. The product may be used in other not-yet-tested applications.

Notes

cELISA : 1:25,000/35,000

FCM : 1:200

IHC:   1:200

Target

S-adenosylhomocysteine is a competitive inhibitor of S-adenosylmethionine-dependant methyl transferase reactions. Therefore, it plays a key role in the control of methylation via regulation of the intracellular concentration of S-adenosylhomocysteine.

Figure 2: Competitive ELISA using anti-S-Adenosymethionine monoclonal antibody [839-12] (MA00308)

The 0.2 pg/ml of SAH-BSA was coated into 96 wells. Serial dilution of SAH standard (SAHNa), S-Adenosylmethionine (SAM: Sigma-Aldrich Cat# A2408), Homocysteine (H-Cys), L-Cysteine (L-Cys), Adenosine (Ade), Glutathione (GST), L- Cystathionine (L-CTT), Methythioadenosine (MTA), ADP (adenosine diphosphate), ATP (adenosine triphosphate) and  properly diluted  MA00308 were added. HRP conjugated Goat anti-Mouse IgG antibody was used to develop the color. OD450 value was measured on each well.

Figure 3: Immunohistochemistry staining was performed using MA00308 with benign liver tissue adjacent to liver cancer. Brown areas indicated positive staining in nuclear and cytoplasmic areas (mainly shown cytoplasmic positive staining). Strong HE staining may affect nuclear SAH positive signals (x400).
