Thermo Scientific Pierce Jacalin Agarose is effective for specific affinity purification of human IgA from serum or colostrum or efficient removal of contaminating IgA from IgG samples.

• Immobilized jacalin specifically binds human IgA1 (does not bind IgG and does not bind human IgA2 or IgA from other species)
• Resin is loaded with approx. 4.5 mg Jacalin/mL resin and effectively binds 1 to 3 mg human IgA1/mL resin
• Agarose resin support is 6% crosslinked beaded agarose, the most popular and versatile resin for protein affinity purification methods

Jacalin is an alpha-D-galactose binding lectin extracted from jack-fruit seeds (Artocarpus integrifolia). This lectin is a glycoprotein (approx. 40 kDa) composed of four identical subunits.
