Product name         

Mouse anti-SAM 2a/b

Catalog Number     

MA00202-50/100

Description              

Mouse monoclonal antibody to S- Adenosylmethionine [84-3]

Specificity                 

Dosage-dependent competition was detected as a sample was added to a cELISA (Any SAM from a sample competes with the coated SAM heptan to bind HRP-conjugated antibody 84-3). The sample is the product of the following biochemical reaction: Methionine Adenosyltransferase (MAT) was added to methionine and adenosine triphosphate under an appropriate buffer at 37°C. It indicates that antibody 84-3 specifically binds physiologically produced SAM.

Cross Reaction

Applications

The use of MA00202 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.

Target

S- Adenosylmethionine is a common co-substrate involved in methyl group transfers. It is made from adenosine triphosphate (ATP) and methionine by methionine adenosyltransferase.Transmethylation, transsulfuration, and aminopropylation are the metabolic pathways that use SAM.Although these anabolic reactions occur throughout the body, most SAM is produced and consumed in the liver.

Cellular localization  

Cytoplasm, nuclear

Figure 1: Immunohistochemistry staining performed using MA00202 with benign liver tissue adjacent to carcinoma.  Brown  areas indicated strong positive staining in cytoplasm (X400).

Figure 2: FCM results from normal liver cell line L02 and hepatocyte carcinoma cell line Hep G2 stained with anti-SAM monoclonal antibody from clone 84-3.Average fluorescence signal in Hep G2 cells was reduced compared to that in L02 cells, indicating SAM level is reduced during carcinogenesis.
