anti-MTA1 Antibody

MTA1

MTA1, MTA-1, Metastasis Associated Protein 1

MTA1 (metastasis-associated protein 1) is a component of the NURD (nucleosome remodeling and histone deacetylation) complex, which is associated with ATP-dependent chromatin-remodeling and histone deacetylase activity. MTA1 functions in conjunction with other components of NURD to mediate transcriptional repression as it facilitates the association of repressor molecules with the chromatin. Structurally, MTA1 contains a single SH3-binding motif and a zinc finger domain, along with a region similar to the co-repressor protein N-Cor. MTA1 is normally expressed at low levels in various tissues and is more highly expressed in testis. Overexpression of MTA1 correlates with tumor invasion and metastasis in various carcinomas including colorectal, gastrointestinal and breast carcinomas. Elevation of MTA1 levels in these tumors appears to enhance the metastases to lymph nodes, increase mammary cell motility and potentiate growth, and therefore may be an indicator for assessing the potential malignancies of various tumors. A similar protein, MTA2, also designated MTA1-L1 (MTA1-like protein 1), shares more than 55% sequence homology with MTA1 and is ubiquitously expressed.

Rabbit

Polyclonal

Rabbit IgG

Human, mouse, rat

Synthetic peptide of human MTA1

N/A

Liquid

100 µl affinity purified rabbit polyclonal antibody in phosphate-buffered saline (PBS) containing 30% glycerol, 0.5% BSA and 0.01% thimerosal.

Affinity purified

Western blot, Immunoprecipitation

Western blotting (1:500 – 1:2000) and immunoprecipitation. However, the optimal concentrations should be determined individually. HeLa cell lysate can be used as positive control. The antibody recognizes the MTA1 of human, mouse, and rat origins. Reactivity to other species has not been tested.

Shelf time: 12 months in temp.: -20 deg.C

gel pack

The antibody solution should be gently mixed before use.

This antibody needs to be stored at + 4°C in a fridge short term in a concentrated dilution. Freeze thaw will destroy a percentage in every cycle and should be avoided.

If you buy Antibodies supplied by Biovision they should be stored frozen at - 24°C for long term storage and for short term at + 5°C.
