The same quick method used for LDL can also be used for Lp(a), with one extra short step, and it likely keeps Lp(a) from getting damaged by air too.
Scientific Claim
Lipoprotein(a) [Lp(a)] can be purified using the same SRUC method plus an additional 30-minute wheat germ agglutinin chromatography step, which also appears to minimize spontaneous oxidative modifications.
Original Statement
“Purification of Lp(a) requires a further wheat germ agglutinin chromatographic step, which can be accomplished within 30 min. More importantly, the method significantly reduces spontaneous oxidation as compared with classical isolation procedures.”
Evidence Quality Assessment

overstated
Study Design Support
Design cannot support claim
Appropriate Language Strength
association
Can only show association/correlation
Assessment Explanation
The abstract implies the oxidation reduction applies to Lp(a) but does not provide direct evidence or comparison data for Lp(a) alone. The claim is inferred from general language and is overstated without validation.
More Accurate Statement
“The SRUC method, with an additional 30-minute wheat germ agglutinin chromatography step, may be associated with reduced spontaneous oxidation in lipoprotein(a) compared to classical methods, based on in vitro observations.”

A Simple and Rapid Purification Procedure Minimizes Spontaneous Oxidative Modifications of Low Density Lipoprotein and Lipoprotein (a)
Scientists found a faster way to clean Lp(a) using a special filter (wheat germ agglutinin) after a quick spinning process, and this new method keeps the Lp(a) from getting damaged by oxygen, unlike older methods.
