Bisulfites, aqueous solutions, n.o.s.
Bisulfite sequencing (also known as bisulphite sequencing) is the use of bisulfite treatment of DNA before routine sequencing to determine the pattern of methylation. DNA methylation was the first discovered epigenetic mark, and remains the most studied. In animals it predominantly involves the addition of a methyl group to the carbon-5 position of cytosine residues of the dinucleotide CpG, and is implicated in repression of transcriptional activity. Treatment of DNA with bisulfite converts cytosine residues to uracil, but leaves 5-methylcytosine residues unaffected Wikipedia

Segregation chart for load, transport, and storage
This chart shows whether loading, transport, or storage with other hazard classes is permitted, prohibited, or restricted. Based on 49 CFR §177.848.
Hinweis: In der Kompatibilitätstabelle sind Stoffe der Gefahrenklasse 8 nur dann zu berücksichtigen, wenn der Stoff flüssig ist. Derzeit kann
HazMat Tool nicht prüfen, ob der Stoff flüssig ist. Dies wird daher hier angenommen. Siehe
PHMSA Interpretation #09-0252.
