Applications

The use of MA00306 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:  1:8,000/20,000
• 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 [844-2] (MA00306)

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  MA00306 were added. HRP conjugated Goat anti-Mouse IgG antibody was used to develop the color. OD450 value was measured on each well.
