Rat IgG Purification Resin and Columns

LigaTrap Technologies is excited to offer our top of the line Rat IgG purification resin. Our Rat IgG purification line can bind all Rat IgG isotypes (IgG1, IgG2a, IgG2b, and IgG2c) from polyclonal and monoclonal sources at a capacity of ≥ 25mg Rat IgG/mL of resin. While Protein A and especially Protein G are commonly used for Rat IgG purification, it is worth noting that Protein A has weak affinity for all but Rat IgG2c, while Protein G has low to no binding of IgG1 and IgG2b.

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.
