Peptide, novel adsorbent, adsorption unit and adsorption method
View Patent ↗The present invention provides an adsorbent, adsorption unit, and an adsorption method which make it possible to selectively adsorb an immunoglobulin and/or an immune complex present in a body fluid (for example, blood, plasma, etc.) efficiently without pretreating the body fluid. By immobilizing a compound having binding activity for an immunoglobulin and/or an immune complex on a water-insoluble carrier, an adsorbent having remarkably excellent adsorption capacity may be obtained.
1. An adsorbent for an immunoglobulin and/or immune complex, the adsorbent comprising a water-insoluble carrier and a peptide immobilized thereon, wherein said peptide consists of the amino acid sequence of SEQ ID NO:10.
2. An adsorbent for an immunoglobulin and/or immune complex, the adsorbent comprising a water-insoluble carrier and a peptide immobilized thereon, wherein said peptide consists of the amino acid sequence of SEQ ID NO:11.
3. An adsorbent for an immunoglobulin and/or immune complex, the adsorbent comprising a water-insoluble carrier and a peptide immobilized thereon, wherein said peptide consists of the amino acid sequence of SEQ ID NO:13.
4. An adsorbent for an immunoglobulin and/or immune complex, the adsorbent comprising a water-insoluble carrier and a peptide immobilized thereon, wherein said peptide consists of the amino acid sequence of SEQ ID NO:15.
5. The adsorbent for an immunoglobulin and/or an immune complex according to any one of claims 1 – 4 , wherein the water-insoluble carrier is porous.
6. The adsorbent for an immunoglobulin and/or an immune complex according to any one of claims 1 – 4 , wherein the water-insoluble carrier is hydrophilic one.
7. The adsorbent for an immunoglobulin and/or an immune complex according to claim 5 , wherein the exclusion limit of molecular weight of the water-insoluble carrier is not less than 150,000.
8. An adsorption unit which comprises the absorbent according to any one of claims 1 – 4 , filled in a container having a liquid inlet and a liquid outlet and equipped with at least one filter.
