: The purified protein is eluted directly onto a target plate using an organic solvent like acetonitrile , where it is mixed with a matrix for analysis. Key Specifications Resin Type : Butyl (C4) silica.

: Enrichment of dilute samples to ensure they are within the detection range of highly sensitive instruments. Role in Mass Spectrometry c4.zip

: Typically optimized for very small volumes (microliters). : The purified protein is eluted directly onto

: Contaminants are washed away with a dilute acid, such as trifluoroacetic acid (TFA) . Role in Mass Spectrometry : Typically optimized for

: The protein sample is aspirated through the tip, binding to the C4 resin.

: Removing salts, buffers, and detergents that interfere with downstream analysis. For example, researchers use them to clean samples of Trastuzumab probes or mussel biotoxins before testing.

: Best for proteins > 10 kDa and highly hydrophobic peptides.
