La resina de agotamiento de HSA/inmunoglobulina Thermo Scientific High Select reduce los componentes de albúmina y anticuerpo que abundan en muestras de plasma humano, lo que ayuda a preparar dichas muestras para la espectrometría de masas o la electroforesis 1D o 2D. La resina se proporciona aquí en un formato práctico de minicolumna de centrifugación de un solo uso para el tratamiento de muestras de 10 µl.

Las características de la resina de agotamiento de HSA/IgG incluyen:
• Flexible: el formato de minicolumna se adapta y optimiza para el tratamiento de muestras de plasma humano de 10 µl
• Optimizado: elimina > 95 % de IgG y > 95 % de albúmina
• Rápido: procesa muestras en ∼ 10 minutos
• Económico: el precio de las columnas de centrifugación rentables es por un solo uso
• Variabilidad reducida: el formato de un solo uso evita el arrastre de proteínas y la variabilidad experimental

La resina de agotamiento de HSA/inmunoglobulina High Select utiliza anticuerpos antiHSA y antiinmunoglobulina inmovilizados altamente específicos (IgG, IgA, IgM, IgD e IgE) para eliminar la seroalbúmina humana (HSA) y todas las subclases principales de inmunoglobulinas de suero y plasma. La resina se suministra en un formato de columna de centrifugación económico y práctico diseñado específicamente para el procesamiento en un solo paso y un solo uso.

Los análisis de fluidos humanos suelen complicarse con frecuencia debido a la presencia de altas concentraciones de albúmina e IgG, que pueden alcanzar más del 70 % del total de las proteínas del suero. La extracción de estas proteínas es a menudo esencial para el estudio de proteínas de baja abundancia. La resina de agotamiento de HSA/inmunoglobulina High Select puede reducir más del 95 % de HSA y el 95 % de IgG. Las muestras se cargan en una columna de centrifugación desechable precargada y se procesan en aproximadamente 10 minutos. El agotamiento de proteínas de alta abundancia ayuda a la detección de proteínas de baja abundancia en las muestras y la posterior identificación mediante espectrometría de masas o electroforesis en gel 1D o 2D.

Preguntas frecuentes

Can I use the High Select Top14 Abundant Protein Depletion Midi Spin Columns to deplete proteins from rodent samples?

The High Select Top14 Abundant Protein Depletion Midi Spin Columns have only been validated for human samples. We do not recommend using them for protein depletion in rodent samples. For protein depletion in rodent samples, we recommend the following multi-species depletion resins:

  • CaptureSelect MultiSpecies Albumin Depletion Product (Cat. No. 191085305)
  • Pierce Albumin Serum Depletion Kits (Cat. No. 89875)


    • Find additional tips, troubleshooting help, and resources within our Protein Purification and Isolation Support Center.

After depletion of abundant proteins from my sample, I still see albumin and other abundant proteins after LC-MS analysis. Did the depletion work?

Depletion does not remove all abundant proteins from the sample. Even with 99% depletion of a specific plasma protein, highly abundant proteins will still be the most abundant proteins in the sample detected by MS analysis. However, depletion significantly decreases the most abundant plasma proteins enabling identification of lower abundant proteins.

Find additional tips, troubleshooting help, and resources within our Mass Spectrometry Support Center.

How do I proceed to downstream mass spec sample preparation after abundant plasma protein depletion?

After the depletion, samples are significantly diluted in buffer. Depleted samples should be concentrated by speed vac drying, solvent precipitation, or diafiltration. Samples dried using a speedvac are directly compatible with the EasyPep kit chemistry after resuspension using the Lysis Solution.

What is the maximum loading capacity for the High Select Depletion columns?

Mini columns can deplete up to 10 µL (600 µg) of plasma or serum; midi columns can deplete up to 100 µL (6000 µg) of plasma or serum.

Find additional tips, troubleshooting help, and resources within our Mass Spectrometry Support Center.

What is the percentage of albumin that is removed using abundant protein depletion columns?

More than 99% of albumin can be depleted when columns use the recommended sample to resin ratio.

Alzheimer's disease (AD) lacks protein biomarkers reflective of its diverse underlying pathophysiology, hindering diagnostic and therapeutic advancements. Here, we used integrative proteomics to identify cerebrospinal fluid (CSF) biomarkers representing a wide spectrum of AD pathophysiology. Multiplex mass spectrometry identified ~3500 and ~12,000 proteins in AD CSF and brain, respectively. Network ... More
