El kit de fraccionamiento de proteínas subcelulares Thermo Scientific para células de cultivo permite la segregación y el enriquecimiento de proteínas de cinco compartimentos celulares diferentes.

Características del kit de fraccionamiento de proteínas subcelulares para células de cultivo:

Conciso: extraiga fracciones de proteínas citoesqueléticas, unidas a cromatina, nucleares solubles, de membrana y citoplasmáticas funcionales de células de mamíferos cultivadas en menos de tres horas
Práctico: realice un procedimiento sencillo sin necesidad de ultracentrifugación por gradientes
Completo: obtenga fracciones de proteínas citoesqueléticas, unidas a cromatina, nucleares solubles, de membrana y citoplasmáticas a partir de un solo kit
Células cultivadas: desarrollado y optimizado para el uso con células de mamíferos cultivadas; para las muestras de tejidos utilice el kit de fraccionamiento subcelular para tejidos
Compatible: utilice extractos para aplicaciones posteriores, como ensayos de proteínas, Western blot, ensayos electroforéticos de cambio de movilidad y ensayos de genes indicadores y de actividad enzimática.

Aplicaciones del fraccionamiento subcelular:
• Extraiga y enriquezca proteínas de diferentes compartimentos celulares
• Aísle proteínas citoplasmáticas, nucleares, de membrana y citoesqueléticas de las mismas células
• Perfile células para proteínas del citoplasma, núcleo, membrana y citoesqueleto
• Estudie la translocación de proteínas

El fraccionamiento de proteínas subcelulares permite la evaluación de la localización de proteínas y el enriquecimiento de proteínas de determinados compartimentos celulares. El kit de fraccionamiento subcelular de proteínas Thermo Scientific incluye una combinación de reactivos para la lisis celular escalonada en fracciones de proteínas citoesqueléticas, unidas a cromatina, nucleares solubles, de membrana y citoplasmáticas en menos de 3 horas. Los extractos de cada compartimento subcelular suelen tener menos del 15 % de contaminación entre fracciones, una pureza suficiente para la mayoría de los experimentos que estudian la localización y redistribución de proteínas.

El kit de fraccionamiento de proteínas subcelulares para células de cultivo contiene cuatro tampones de extracción, una nucleasa estabilizada y un cóctel inhibidor de proteasa Thermo Scientific Halt. Cada kit contiene suficientes reactivos para fraccionar 50 sedimentos de células de 20 µl cada uno, lo que equivale a aproximadamente 2 g de pasta celular. (Para muestras de tejidos, utilice nuestro kit de fraccionamiento de proteínas subcelulares para tejidos).

Cuando el primer reactivo del kit se agrega a un sedimento celular, causa la permeabilización selectiva de la membrana, liberando el contenido soluble del citoplasma. El segundo reactivo disuelve las membranas de ER-golgi, mitocondrias y plasma, pero no solubiliza las membranas nucleares. Tras recuperar por centrifugación los núcleos intactos, un tercer reactivo produce el extracto nuclear soluble. Se realiza una extracción nuclear adicional con nucleasas de micrococos para liberar las proteínas nucleares unidas a cromatina. El sedimento insoluble recuperado se extrae con el reactivo final para aislar las proteínas citoesqueléticas.

Preguntas frecuentes

What products are available for the isolation of subcellular components?

You can choose from several types of Dynabeads magnetic beads for coating with antibody against the subcellular component of choice. We currently do not offer any ready-to-use Dynabeads magnetic beads against a particular subcellular component, and recommend that you choose the beads that work best with your antibody and your application.

The following groups of Dynabeads magnetic beads can be used for this purpose:

(1) Surface Activated Dynabeads magnetic beads
Antibodies from any origin can be conjugated directly to these uncoated beads through covalent bonds. For better orientation of primary antibody on the beads, a secondary antibody (linker antibody) can be coated on the beads first. The Surface Activated Dynabeads magnetic beads are provided in different sizes (4.5, 2.8 and 1 micron) and the larger ones are mostly preferred for this application.

(2) Secondary Coated Dynabeads magnetic beads
These Dynabeads magnetic beads are pre-coated with a secondary antibody and depending on their specificity, they can be easily coated with your primary antibody within a short time period. These beads are provided in two sizes, 4.5 and 2.8 micron. In addition to these beads, our Dynabeads magnetic beads Protein A or Protein G can also be easily coated with antibody from several species. Please see the following links for information about all available Secondary coated Dynabeads magnetic beads and Dynabeads magnetic beads Protein A and Protein G.

(3) Streptavidin Coated Dynabeads magnetic beads
These Dynabeads magnetic beads are coated with streptavidin and require a biotinylated antibody. These beads are provided in two different sizes, 2.8 and 1 micron.

Can you provide the shelf-life for the Subcellular Protein Fractionation Kit for Cultured Cells?

The Subcellular Protein Fractionation Kit for Cultured Cells is covered under our general 1-year warranty and is guaranteed to be fully functional for 12 months from the date of shipment, if stored as recommended. Please see section 8.1 of our Terms & Conditions of Sale (https://www.thermofisher.com/content/dam/LifeTech/Documents/PDFs/Terms-and-Conditions-of-Sale.pdf) for more details.

Can I use the Subcellular Protein Fractionation Kit for Cultured Cells (Cat. No. 78840) for subsequent co-immunoprecipitation (co-IP) analysis of different nuclear proteins?

Yes, the nuclear fraction is compatible with co-immunoprecipitation (co-IP) after dialysis, desalting, or 50:50 dilution. The cytoplasmic and membrane fractions are compatible with co-IP directly after extraction and the pellet fraction is compatible with co-IP after detergent removal.

Will M-PER Mammalian Protein Extraction Reagent extract membrane or cytoskeletal proteins?

M-PER Mammalian Protein Extraction Reagent can extract some membrane or cytoskeletal proteins, but the extraction efficiency is not consistent. The reagent was not intended to specifically extract these proteins. We recommend using Mem-PER Plus Membrane Protein Extraction Kit (Cat. No. 89842) for membrane protein extraction or Subcellular Protein Fractionation Kit for Cultured Cells (Cat. No. 78840) for compartmental extraction.

Abstract
DRIM modulates Src activation and regulates angiogenic functions in vascular endothelial cells.
Authors:Tong J,Dong X,Martin TA,Yang Y,Dong B,Jiang WG
Journal:Cell biology international
PubMed ID:39648301
Downregulated in Metastasis Protein (DRIM) was discovered in malignant epithelial cells and was thought to be mainly a nucleus protein affecting cancer cells. Recent single-cell sequencing analysis suggests that DRIM is abundantly expressed in vascular endothelial cells. There has been no knowledge of the role of DRIM in the endothelium. ... More

Since the start of mass-spectrometry-based proteomics, proteins from non-referenced open reading frames or alternative proteins (AltProts) have been overlooked. Here, we present a protocol to identify human subcellular AltProt and decipher some interactions using cross-linking mass spectrometry. We describe steps for cell culture, in cellulo cross-link, subcellular extraction, and sequential digestion. ... More

Repurposing PARP-1 inhibitors (PARPi) for non-oncological applications offers an attractive therapeutic strategy for pathological conditions characterized by PARP-1 hyperactivity. In the context of Parkinson's disease (PD), PARP-1 hyperactivity has been linked to neuronal death and disease progression. From a therapy perspective, the evaluation of PARPi as neuroprotective agents may offer ... More
