Partículas magnéticas de estreptavidina

Los kits de preparación de muestras Thermo Scientific SureQuant IP-MS (proteína A/G o estreptavidina) proporcionan una solución optimizada para la inmunoprecipitación y la preparación de péptidos de MS de muestras antes del análisis de LC-MS/MS. Estos kits se han verificado rigurosamente utilizando numerosos antígenos objetivo multiplexados con diferentes niveles de expresión. La familia de productos SureQuant permite el uso de kits de preparación de muestras de inmunoprecipitación (IP) y módulos de cuantificación de péptidos juntos o de forma independiente para el análisis SRM/PRM.

Complete—kits include reagents for successful immunoprecipitation and MS peptide preparation for target proteins for SRM/PRM analysis
Multiplex—IP-MS kits have been designed for multiplex IP using both Protein A/G and Streptavidin magnetic beads
Flexible—universal reagents enable individualized selection of targets for IP to be used alone or combined with SureQuant peptide quantitation panels
Optimized—simplified and condensed procedure to prepare samples for LC-MS analysis
Low background—binding, wash, and elution buffers optimized to remove contaminants and minimize enrichment of background proteins

The SureQuant Protein A/G and Streptavidin IP-MS Sample Preparation kits have been designed to support targeted quantitation using SureQuant or SRM/PRM analysis. The kits contain high-quality Pierce Protein A/G or Streptavidin magnetic beads together with reagents that have been optimized for MS compatibility. The streamlined procedure enables digestion immediately after the immunoprecipitation elution step, facilitating MS sample preparation in ∼4 hours for same-day LC-MS/MS analysis.

Applications:
• Enrichment of low abundance targets to improve MS sensitivity
• Identification of target proteins that are not detectable by western blotting
• Quantitation of target proteins by LC-MS analysis
• Screening of antibodies for IP-MS
• Enrichment of target proteins upstream of targeted analysis (SRM)

Preguntas frecuentes

Why is the processing time for MS analysis less with SureQuant IP-MS Sample Preparation kits compared to traditional IP methods?

SureQuant Protein IP-MS Sample Preparation kits use a trypsin enzyme elution method to dissociate the bound immune complexes from the magnetic beads, which can then be digested directly in-solution and followed up by MS analysis on the same day; no SDS-PAGE purification is required. The entire process take 4 hours compared to traditional IP methods that usually take around 21 hrs.

What is the difference between SureQuant IP-MS Sample Preparation kits and Pierce MS-Compatible Magnetic IP kits?

SureQuant IP-MS Sample Preparation kits include all reagents necessary for sample lysis, immunoenrichment, elution, digestion, and MS analysis. The entire process is completed in 4 hr for same-day LC-MS/MS analysis as compared to traditional IP methods that usually take around 21 hr. Pierce MS-Compatible Magnetic IP kits provide reagents necessary for the lysis step and the elution step, but not for the digestion step prior to MS analysis.

Can I use SureQuant Protein A/G and SureQuant Streptavidin IP-MS Sample Preparation kits with any sample?

SureQuant IP-MS sample preparation kits have been designed for use with SureQuant quantitation modules for upstream sample preparation for SRM/PRM analysis, but they can be used with any samples where the target protein needs to be enriched by IP or IP-CoIP, prior to MS analysis.
