Description du produit
- Isolates pure nuclei from animal cells and tissues (soft: liver/brain, hard: muscle, cultured)
- Applications: cell death (apoptosis), signaling, metabolism & protein studies
- Nuclei free from protein & nuclease contamination
Protocole
La préparation des échantillons:
- Tissues:
- Take 100-200mg fresh tissue (liver, brain, heart)
- Wash with PBS/saline, sec, cut into small pieces
- Homogenize with 1ml pre-cooled Ly10is buffer & 50µL Reagent A (ice bath, 20X)
- Cultured Cells:
- Digest and wash cells
- Centrifuger (5-10min, 800g), jeter un surnageant, collect & compter les cellules
- Resuspend 5×10^7 cells in 1ml pre-cooled Lysis Buffer
- Add 50µL Reagent A, homogenize (ice bath, 20-30X)
Nuclear Isolation:
- Transfer homogenate to a 1.5ml centrifuge tube.
- Centrifuger (5min, 700g, 4°C), jeter un surnageant (nuclear pellet remains).
- Resuspend nuclear pellet with 0.5ml pre-cooled Lysis Buffer.
- Transfer to a new tube containing 0.5ml Medium Buffer (layered carefully).
- Centrifuger (5min, 700g, 4°C), jeter un surnageant (nuclear pellet remains).
- Resuspend nuclear pellet with 5ml Medium Buffer.
- Centrifuger (10min, 1000g, 4°C), jeter un surnageant (purified nuclei pellet).
Stockage:
- Resuspend purified nuclei in 50-100μl Store Buffer or desired buffer.
- Nuclei are ready for use or can be stored at -70°C
Remarques:
Ensuring Complete Nuclei:
- Low Temperature: Perform the entire procedure at a low temperature.
- Vitesse: Work quickly throughout the process.
- Cell Disruption: The key is to break cells without damaging organelles.
- Tissues: Use a small-capacity glass homogenizer with a tight-fitting pestle for efficient homogenization.
- Cultured Cells: Breaking adherent cells is more challenging. Utilize the small homogenizer and tight pestle for optimal results.
Centrifugation:
- Calculate the correct centrifugal speed (RPM) based on the desired relative centrifugal force (RCF or g-force) using the formula:
- G = 1.11 x 10^-5 x R x (RPM)^2
- g: FCR (g)
- RPM: Rotations per Minute (squared)
- R: Rotor Radius (cm)
Applications en aval:
-
- For Western Blot and 2D-PAGE, directly lyse the nuclear sample by adding loading buffer.
