Applications

The use of MA00304 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.

Notes

• FCM:   1:100
• IHC:   1:100

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 [301-16]

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  MA00304 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 MA00304 with benign  liver tissue adjacent to carcinoma.   Brown areas indicated strong positive staining in nuclear and cytoplasmic areas(x400).

Figure 3: The same samples as in Figure 2 from liver cancer area. Cytoplasmic and nuclear areas showed negative and some background staining (probably extra antibody was used) (x400).
