Alicyclic structure-containing polymer resin container and optical analysis method using the container

Abstract

A container for optical analysis composed of a bottom portion and a sidewall portion, wherein the bottom portion and the sidewall portion are made by a resin containing an alicyolic structure, and surface roughness Ra is 1 μm or less, at the point where light for the optical analysis passes through, in the area where the bottom portion and the sidewall portion contacts with the measuring subject therefor.

1 . A container for optical analysis composed of a bottom portion and a sidewall portion, 
 wherein said bottom portion and said sidewall portion are made by a resin containing an alicyclic structure, and    surface roughness Ra is 1 μm or less, at the point where light for the optical analysis passes through, in the area where the bottom portion or the sidewall portion contacts with the measuring subject therefor.    
   
   
       2 . The container as set forth in  claim 1 , wherein thickness of said bottom portion and sidewall portion is 3 mm or thinner.  
   
   
       3 . The container as set forth in  claim 1 , wherein surface roughness Ra is 1 μm or less at the point where the light for optical analysis does not pass in said bottom portion and sidewall portion.  
   
   
       4 . The container as set forth in  claim 2 , wherein absorbance at a wavelength of 240 to 400 nm is 0.4 or lower at said thickness.  
   
   
       5 . The container as set forth in  claim 1 , wherein said alicyclic structure containing polymer is a norbornene based polymer or hydrogenate of the same.  
   
   
       6 . The container as set forth in  claim 1 , wherein said resin containing alicyolic structure is hydrogenated ring-opening polymer of a norbornene based monomer.  
   
   
       7 . The container as set forth in  claim 1 , wherein a residual metal content in said resin containing alicyclic structure is 100 ppm or less.  
   
   
       8 . The container as set forth in  claim 1 , wherein the measuring subject includes DNA or RNA.  
   
   
       9 . The container as set forth in  claim 1 , which is a multi-well plate.  
   
   
       10 . An optical analyzing method of a measuring subject comprising the steps of: 
 putting the measuring subject into a container composed of a bottom portion and a sidewall portion, wherein the bottom portion and the sidewall portion are made by a resin containing alicyclic structure, and surface roughness Ra is 1 μm or less, at the point where light for the optical analysis passes through, in the area where the bottom portion or the sidewall portion contacts with the measuring subject therefor; and    performing optical analysis on a measuring subject by using light having a wavelength of 240 to 400 nm.    
   
   
       11 . The analyzing method as set forth in  claim 10 , wherein the measuring subject includes DNA or RNA.
