Note: many chromatin-bound proteins are not soluble in a low salt nuclear extract and fractionate to the pellet. Therefore, we recommend a High Salt / Sonication Protocol when preparing nuclear extracts for Western Blot.


This antibody was raised against a peptide within the C-terminal region of human WDR5.


Purified IgG in PBS with 30% glycerol and 0.035% sodium azide. Sodium azide is highly toxic.

WDR5 (WD repeat-containing protein 5) is a component of the Set1 histone methyltransferase / MLL1/MLL complex that is involved in methylation and dimethylation of 'Lys-4' of Histone H3. H3K4 methylation represents a specific tag for epigenetic transcriptional activation. WDR5 is also a component of the NSL complex and it may be involved in acetylation of nucleosomal histone H4 on several lysine residues. WDR5 is also core component of other methyltransferase-containing complexes including MLL2/3 (also named ASCOM complex) and MLL4/WBP7.


Some products may be shipped at room temperature. This will not affect their stability or performance. Upon receipt, unconjugated antibodies may be stored at -20°C for up to 2 years. Fluorophore- & enzyme-conjugated antibodies should be stored at 4°C. Fluorophore-conjugated antibodies should be protected from light. Keep reagents on ice when not in storage; to avoid repeated freeze/thaw cycles, we recommend aliquoting items that will be stored frozen into single-use fractions prior to freezing.
