Human IgA Purification Resin and Columns

In the past, Immunoglobulin A (IgA) has been one of the more difficult antibodies to purify due to the lack of a robust and high capacity affinity resin. Fortunately for IgA researchers, this has changed with the introduction of the LigaTrap Human IgA Purification line. With binding capacities of ≥15mg IgA/mL resin, this IgA purification resin far exceeds the capacity of Pierce^TM Jacalin and other lectin-based resins commonly used.. On top of this, LigaTrap Human IgA Resin does not require the use of sugar (galactose, sucrose, etc.) based elution buffers, therefore simplifying further downstream processing. The resin binds both IgA1 and IgA2 subclasses and can be used for up to 100 cycles after sanitization.

In addition to increased yields and purity levels, LigaTrap Technologies address many of the shortfalls related to standard affinity ligands including challenges.  Our peptide ligands provide for a robust lifecycle, mild elution conditions and no immunogenicity or leaching.

This product is not recommended in serum purification applications due to cross-reactivity with other immunoglobulins. Please consult LigaTrap for protocols that may improve results in serum.
