One embodiment shows a method for producing porous cellulose particles, including:

Method for producing porous cellulose particles, and porous cellulose particles

An adsorbent, which can be produced by a method in which a particle size, a pore size, a specific surface area or the like can be easily controlled, and is suitable for isolation of biomolecules. The adsorbent contains aggregates of calcium phosphate-based particles, and has an average pore size of 15 to 36 nanometers and a specific surface area of 40 to 90 m/mL when measurement is carried out by mercury porosimetry.

Adsorbent and method for producing the same

An object is to provide a method for producing an ever-larger molecular weight collagen-like polypeptide single strand. Another object is to provide a method for controlling a molecular weight of a product to be obtained in desired magnitude upon producing a collagen-like polypeptide single strand. A solution is a method for producing a polypeptide including a step for allowing a condensation reaction of peptide oligomers represented by any one of formulas (1) to (3) (SEQ ID No:1 to SEQ ID No:3), wherein the condensation reaction is carried out in an aqueous solvent containing a phosphate ion in the range of 0 M to less than 0.01 M in the presence of a condensing agent, or a condensing agent and a condensing auxiliary:H-(Pro-Y-Gly)-OH&#x2003;&#x2003;(1);H-(Y-Gly-Pro)-OH&#x2003;&#x2003;(2); andH-(Gly-Pro-Y)-OH&#x2003;&#x2003;(3);wherein, in formulas (1) to (3), Y is hydroxyproline or proline, and n is an integer from 1 to 10.
