[Performance Evaluation]

Antiviral Performance Evaluation
Test sample: PVC sheet containing 1.5% SR-AVP-803

Test Method:
1. Inoculate the test specimen with 0.4 mL of viral suspension and cover with a sealing film.
2. Hold in a temperature-controlled chamber at 25°C for 24 hours, then recover the virus by washing.
3. Determine the viral infectivity titer using a plaque assay.
Sealing film: PE

Test Virus 1:
Influenza A virus (H3N2), strain ATCC VR-1679
Host cells: MDCK cells (derived from canine kidney)

Test Virus 2:
Feline calicivirus (F-9), strain ATCC VR-782
Host cells: CRFK cells (derived from feline kidney)

Test Virus 1: Influenza Virus

Test Specimen	Contact Time	Viral Infectivity Titer Mean Log10 Value	Antiviral Activity Value
Control (PE Film)	Immediately after Inoculation	7.8
	After 24 Hours	6.8
PVC Sheet with 1.5% SR-AVP-803	After 24 Hours	2.0	4.8

Test Virus 2: Feline Calicivirus

Test Specimen	Contact Time	Viral Infectivity Titer Mean Log10 Value	Antiviral Activity Value
Control (PE Film)	Immediately after Inoculation	6.6
	After 24 Hours	6.1
PVC Sheet with 1.5% SR-AVP-803	After 24 Hours	4.0	2.1

Antiviral Activity Value (Mean Log10 Value)= Viral infectivity titer of the control after 24 hours − viral infectivity titer of the treated sample

[Precautions]
* Before use, conduct thorough testing to confirm the quality and physical properties of the product after adding SR-AVP-803.
