Histone H10 Human, RecombinantProduct information
|100 µg ( 1 mg/ml )||-||Unavailable in your region|
DescriptionHistone H1 acts on the linker region of polynucleosome DNA to condense the chromatin into structures of ~30 nm (1). It is not necessary for octamer or nucleosome core particle formation. Eight different Histone H1 proteins have been identified in the human genome (2). Histone H10 is a non replication-dependent histone that is highly expressed in cells that have terminally differentiated (3).

Quality Control AssaysThe following Quality Control Tests are performed on each new lot and meet the specifications designated for the product. Individual lot data can be found on the Product Summary Sheet/Datacard or Manual which can be found in the Supporting Documents section of this page.
- Endonuclease Activity (Nicking):
The product is tested in a reaction containing a supercoiled DNA substrate. After incubation for 4 hours the percent converted to the nicked form is determined by agarose gel electrophoresis.
- Exonuclease Activity (Radioactivity Release):
The product is tested in a reaction containing a radiolabeled mixture of single and double-stranded DNA. After incubation for 4 hours the exonuclease activity is determined by the % release of radioactive nucleotides.
- Molecular Weight Determination (Mass Spectrometry) :
The molecular weight of the product is determined using mass spectrometry.
- Protease Activity (SDS-PAGE):
The product is tested for protease activity by incubation with a standard mixture of proteins resulting in no detectable degradation of the proteins as determined by SDS-PAGE.
- 1 mg/ml, 48 µM is calculated using the molar extinction coefficient for Histone H1 (3840) and its absorbance at 280 nm (4,5). 1.0 A280 units = 5.4 mg/ml.
- There is a small percentage of Histone H10 with a mass of 20863.27 which is a +131 Da difference from the major species. This correlates to Histone H10 with an intact N-terminal methionine (6).
