This invention is about a cell-penetrating drug carrier and the application thereof. The mentioned cell-penetrating drug carrier can approach the target cell through using a proper recognizable sequence, so that the cell-penetrating drug carrier can be used to specifically delivery wanted drug to target cell. Through carrying wanted drug into the cytoplasm of the target cell by cell-penetrating peptide, the drug accumulation volume in the target cell can be efficiently increased. Preferably, through using proper bioinert polymer, the cell-penetrating peptide and the recognizable sequence can be kept from been digested before approaching the target cell.

Cell-penetrating drug carrier and the application thereof

A method of purifying a compound from a mixture through a chromatographic column loaded with a column adsorbent. The method comprises:

Peptide chromatographic purification assisted by combining of solubility parameter and solution conformation energy calculations

Specifically, the present invention relates to an asymmetric porous PTFE membrane for a filter comprising a dense skin layer and a continuously foamed porous layer, wherein

Asymmetric porous polytetrafluoroethylene membrane for a filter

The present invention provides an asymmetric porous PTFE membrane for clothing having little change over time and conventionally known properties of a porous PTFE molded article such as water permeability resistance, air permeability, sealing properties and electric properties, in which durability and water vapor permeability are improved by strengthening adhesion strength with fabric. Specifically, the present invention relates to an asymmetric porous PTFE membrane for clothing comprising a dense skin layer and a continuously foamed porous layer, wherein (1) the contact angle of water to the surface of the skin layer is 120 to 140&#xb0;; and (2) the diffuse reflectance of light of the skin layer is 91 to 94%.

Asymmetric porous polytetrafluoroethylene membrane for clothing

The present invention relates to an asymmetric porous polytetrafluoroethylene membrane comprising a dense skin layer and a continuously foamed porous layer, (1) the dense skin layer having a surface roughness Ra of 20 to 165 nm; (2) the dense skin layer having a contact angle for water of 120 to 135&#xb0;; (3) the porous layer having a maximum pore diameter of 0.03 to 1.0 &#x3bc;m; and (4) the membrane having a total porosity of 20 to 70%. The asymmetric porous PTFE membrane has an ability to separate each liquid component from a liquid-liquid homogeneous mixture in addition to known properties such as water permeability resistance, gas permeability, sealing property and electric property, wherein change of these properties over time is small.
