Product Overview:
Enhancer of zeste homolog 2 (EZH2) is a histone-lysine N-methyltransferase enzyme (EC 2.1.1.43) encoded by EZH2 gene, that participates in DNA methylation and, ultimately, transcriptional repression. EZH2 catalyzes the addition of methyl groups to histone H3 at lysine 27, by using the cofactor S-adenosyl-L-methionine. Methylation activity of EZH2 facilitates heterochromatin formation thereby silences gene function. Remodeling of chromosomal heterochromatin by EZH2 is also required during cell mitosis. EZH2 is the catalytic subunit of the Polycomb repressive complex 2 (PRC2). EZH2's catalytic activity relies on its formation of a complex with at least two other PRC2 components, SUZ12 and EED. As a histone methyltransferase (HMTase), EZH2's primary function is to methylate Lys-27 on histone 3 (H3K27me) by transferring a methyl group from the cofactor S-adenosyl-L-methionine (SAM), although recent studies have indicated that it is also capable of methylating non-histone proteins. EZH2 is capable of mono-, di-, and tri-methylation of H3K27 and has been associated with a variety of biological functions, including transcriptional repression and activation, hematopoiesis, development, and cell differentiation.
Usage:
Reconstitute in PBS or others.
Stability:
The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37°C for 48h, and no obvious degradation and precipitation were observed. The loss rate is less than 5% within the expiration date under appropriate storage condition.
Storage:
Store it under sterile conditions at -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles. Samples are stable for up to twelve months from date of receipt at -80℃.
Stroage Buffer:
PBS (58mM Na2HPO4, 17mM NaH2PO4, 68mM NaCl, pH7.). 5 % trehalose and 5 % mannitol are added as protectants before lyophilization.

Precautions:
This product is for research use only, not for diagnostic or therapeutic use.
