The sample preprocessing stage in proteomics experiments is a critical step to ensure the accuracy and consistency of experimental results. Given the complexity and numerous steps involved in the sample preprocessing workflow, developing an integrated and standardized experimental procedure is crucial for addressing the challenges in proteomics sample preprocessing. The SISPROT^?^ technology launched by BePepBio in 2023 is an integrated proteomics preprocessing technology based on the centrifugal pipette tip "Spintip". It enables one-stop completion of all steps in proteomics sample preprocessing from the crude sample, including protein sample pre-enrichment, reduction, alkylation, enzymatic digestion, and desalting. The processed samples can be directly used for LC-MS/MS analysis. This technology combines high sensitivity, high throughput, and high stability, making it particularly suitable for protein samples in the low microgram or even nanogram range.

Product Features

High Efficiency: Complete sample processing within 2 hours

While traditional methods require 16 hours, the SISPROT Kit completes all sample preprocessing steps within 2 hours, and the processed samples are ready for direct instrumental analysis.

?

High Sensitivity: Approximately 6000 proteins detected from 100ng
Approximately 6000 proteins can be stably detected from 100ng. The minimum initial sample amount can be as low as 1ng (equivalent to ~10 cells).

?

High Stability: Excellent quantitative reproducibility across different operators
