Description
CUTANA™ Nuclei Extraction Buffer is the essential reagent for harvesting nuclei from cultured cells and tissues for use in CUT&RUN and CUT&Tag assays. This buffer is expected to be broadly compatible with eukaryotic cells and tissues. Below are examples of various cells and tissue types that have undergone successful nuclei isolation using this buffer:
mouse NIH3T3 fibroblast cells | human A549 non-small cell lung cancer (NSCLC) cells |
human K562 leukemia cells | human NCI-H1299 non-small cell lung cancer (NSCLS cells) |
human bone marrow derived macrophages | human TIG-1 fetal lung cells |
human monocyte derived macrophages | human LoVo colorectal cancer cells |
human MV-4-11 macrophage cells | human LNCaP prostate carcinoma cells |
human SUM149 triple negative breast cancer (TNBC) cells | human renal primary cells |
human GM24385 B-lymphocyte (aka HG002) cells | human peripheral blood mononuclear cells (PBMCs) |
human MCF7 breast cancer cells | human intestinal tissue |
human MDA-MB-231 breast cancer cells | human HEPM embryonic cells |
human SK-MEL-2 melanoma cells |
The reagent is prepared by supplementing Pre-Nuclei Extraction Buffer with protease inhibitor and spermidine fresh on the day of use. Utilize this buffer in EpiCypher’s CUTANA™ Nuclei Extraction Protocol for CUT&RUN and CUT&Tag to obtain the highest quality nuclei for your genomic mapping assay.
Validation Data
Figure 1: Nuclei Extraction
Nuclei were extracted from 3 different cell
types: K562, NIH3T3, and LNCaP using the CUTANA™ Nuclei Extraction
Protocol for CUT&RUN and CUT&Tag. Top 3 panels show cells before
extraction. Starting cells are viable (bright white and round). Bottom 3
panels show nuclei extracted using the CUTANA™ Nuclei Extraction Buffer
as indicated by positive Trypan Blue staining.

Technical Information
Prepare Nuclei Extraction Buffer FRESH on day of use as outlined below. This master mix includes 20% extra volume to account for pipetting error; no additional buffer volume is needed.
Per CUT&RUN or CUT&Tag reaction, combine:
235 µL Pre-Nuclei Extraction Buffer (21-1026a)
0.13 µL 1M Spermidine (21-1026b)*
9.8 µL 25X Protease Inhibitor (Roche, prepare by dissolving 1 tablet in 2 mL water)**
*If preparing buffer for fewer than 8x reactions, dilute the 1M Spermidine stock 1:10 in molecular biology-grade water and add 1.3 µL per reaction.
**Leftover 25X Protease Inhibitor can be stored for 12 weeks at -20ºC
Follow instructions detailed in EpiCypher’s CUTANA™ Nuclei Extraction Protocol for CUT&RUN and CUT&Tag to isolate nuclei from suspension and adherent cells. The protocol includes key quality control checks to ensure nuclei are high quality before starting CUT&RUN or CUT&Tag.
