Abstract: A material removes neutrophils while suppressing removal of platelets, the material being a knitted fabric or a woven fabric including a fiber having a fiber diameter of 10 to 60 ?m, wherein the knitted fabric or the woven fabric has a thickness of 0.10 to 0.40 mm and a porosity of 10 to 30%.

Abstract: A protein that recognizes a drug moiety of an antibody-drug conjugate in which a drug represented by the following formula is conjugated to an antibody via a linker, and a method for quantifying the concentration in plasma of an antibody-drug conjugate in a mammal to which the antibody-drug conjugate has been administered, by using the protein, and a method for identifying a tissue distribution of an antibody-drug conjugate.

Abstract: A DDS compound comprising a carboxy(C1-4)alkyldextran polyalcohol modified with a saccharide compound and a residue of drug compound bound to the carboxy(C1-4)alkyldextran polyalcohol, and a method for measuring a DDS compound in which a polymer carrier and a residue of drug compound are bound to each other by means of a spacer comprising 2 to 8 amino acids linked by peptide bond(s), which comprises the steps of treating the DDS compound with a peptidase, and measuring the resulting hydrolysate.

Abstract: A drug complex characterized in that a residue of a drug compound such as antineoplastic agents and a carboxy(C1-4)alkyldextran polyalcohol obtained by treating a dextran under conditions that enable substantially complete polyalcoholization are bound to each other by means of a spacer comprising an amino acid or a spacer comprising peptide-bonded 2 to 8 amino acids. Said complex is characterized in that it has excellent selectivity to tumorous sites so as to exhibit high antineoplastic activity and also achieves reduced appearance of toxicity.

Abstract: A drug complex useful as a DDS compound, which is represented by the following formula: A-R—NH—Y—CH2—O—CO-Q, wherein A is a polymer as a drug carrier; R is a spacer, wherein the spacer is an amino acid or an oligopeptide comprising 2 to 8 amino acids; Y is phenylene group which may be substituted; and Q is a residue of a drug compound such as antineoplastic agents. The complex provides rapid and site-selective release of a drug compound such as antineoplastic or anti-inflammatory agents and surely exhibits expected efficacy.

Abstract: A drug delivery system compound comprising a carboxy(C1-4)alkyldextran polyalcohol modified with a saccharide compound and a residue of drug compound bound to the carboxy(C1-4)alkyldextran polyalcohol, and a method for measuring a drug delivery system compound in which a polymer carrier and a residue of drug compound are bound to each other by a spacer comprising 2 to 8 amino acids linked by peptide bond(s), which comprises treating the drug delivery system compound with a peptidase, and measuring the resulting hydrolysate.
