MaxLight™650 is a new Far-IR stable dye conjugate comparable to Alexa Fluor™647, DyLight™649, Cy5™ and offers better labeling efficiency, brighter imaging and increased immunodetection.
Histone H3 is one of the 5 main histone proteins involved in the structure of chromatin in eukaryotic cells.
Featuring a main globular domain and a long N terminal tail H3 is involved with the structure of the nucleosomes of the 'beads on a string' structure.
Acetylation of histone H3 occurs at several different lysine positions in the histone tail and is performed by a family of enzymes known as Histone Acetyl Transferases (HATs).
Applications:Suitable for use in Western Blot, Peptide Inhibition, Immunocytochemistry, Chromatin Immunoprecipitation, Beadlyte Histone-Peptide Specificity Assay and Dot Blot.
Other applications not tested.
Recommended Dilution:Western Blot: 0.5ug/ml detects dimethylated histone H3 in acid extracted proteins from HeLa cells.
No detection of 1ug unmethylated recombinant Histone H3 (H5110-12K) was observed.
Peptide Inhibition: 1uM of the immunizing peptide to completely abolishes detection of histone H3 in Western Blot analysis of HeLa acid extracts.
Slight signal reduction was observed with peptide containing dimethyl-lysine 9.
Signal was not reduced by branched monomethyl H3(Lys27), linear monomethyl H3(Lys27), linear trimethylH3(Lys27), or linear dimethyl H3(Lys4) peptides
Beadlyte Histone-Peptide Specificity Assay: 12.5ng/ml or a range of dilutions detected peptides containing the dimethyl-lysine modification at residue 27.
Peptides containing other modifications were not detected
Optimal dilutions to be determined by the researcher.
Storage and Stability:Store product at 4°C in the dark.
DO NOT FREEZE! Stable at 4°C for 12 months after receipt as an undiluted liquid.
Dilute required amount only prior to immediate use.
Further dilutions can be made in assay buffer.
Caution: MaxLight™650 conjugates are sensitive to light.
For maximum recovery of product, centrifuge the original vial prior to removing the cap.
Note: Applications are based on unconjugated antibody.
