Histone H4 Protein (3meLys5)

N° du produit ABIN2669555

Détail du produit

Antigène: Histone H4

Type de proteíne: Recombinant

Attributs du protein: 3meLys5

Origine: Xenopus laevis

Source: Escherichia coli (E. coli)

Application: Positive Control (PC), Substrate (S)

Attributs du produit: Recombinant Xenopus laevis Histone H4 trimethyl Lys5 (H4K5me3) is produced in E. coli and purified using FPLC. Recombinant methylated histones are specifically methylated via a chemical alkylation reaction that introduces a methyl lysine analog (MLA). This specific chemical treatment enables the site and degree of methylation to be controlled precisely. Each methylation reaction is over 99 % complete, as verified by high-resolution ESI-TOF mass spectrometry. Protein concentration was determined using the molar extinction coefficient for Histone H4 and absorbance at 280nm. The recombinant histone is >98 % pure by SDS-PAGE. The molecular weight of the recombinant histone is 11,297 Daltons.

Purification: Purified using FPLC

Pureté: The recombinant histone is >98 % pure by SDS-PAGE.

Information d'application

Indications d'application: Recombinant histones are suitable for use as positive controls in the analysis of histone post-translational modifications, as substrates for histone modification enzymes, or to generate chromatin in vitro.

Restrictions: For Research Use only

Stockage

Format: Lyophilized

Reconstitution: Recombinant histones can be resuspended in water or any suitable buffer. We recommend a starting concentration of 1 mg/mL. To fully solubilize the histone we suggest resuspension in the buffer of choice at room temperature for 20-30 minutes with occasional pipetting. Addition of salt or Tris to the resuspension buffer may enhance histone solubility.

Conseil sur la manipulation: Avoid repeated freeze/thaw cycles and keep on ice when not in storage.

Stock: -20 °C/-80 °C

Stockage commentaire: Lyophilized proteins can be stored at -20°C or -80°C, preferably desiccated. Recombinant proteins in solution are temperature sensitive and must be stored at -80°C to prevent degradation.

Sujet: Histone H4 is one of the core components of the nucleosome. The nucleosome is the smallest subunit of chromatin and consists of 146 base pairs of DNA wrapped around an octamer of core histone proteins (two each of H2A, H2B, H3 and H4). Histone H1 is a linker histone, present at the interface between the nucleosome core and DNA entry/exit points.

Poids moléculaire: The molecular weight of the recombinant histone is 11,297 Daltons.
