Applications

The use of MA00303-50 in the following tested applications has been tested. 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.

• 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.

Cellular localization

Cytoplasm, nuclear

Figure 1:  Competitive ELISA using anti-S-Adenosymethionine monoclonal antibody [301-3] (MA00303)

The 0.5 pg/ml of SAH-BSA was  coated  into 96  wells. Serial dilution of SAH  standard (SAHNa),  S- Adenosylmethionine (SAM from 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   MA00303 were added. HRP conjugated Goat anti-Mouse IgG antibody was used to develop the color. OD450 value was measured on each well.

Figure 2: Immunohistochemistry staining was performed using MA00303 with benign  liver tissue  adjacent to carcinoma.   Brown areas indicated strong positive staining in nuclear and cytoplasmic areas (x400).
