Application

There are 5 measurement modules provided by K5500 software: Nucleic acid, Protein, Cell culture, Microarray and UV-VIS.

Nucleic Acid: Concentration and purity of DS-DNA, SS-DNA and RNA

Protein:    Concentration of the protein A280(1Abs = 1mg/mL), BSA, IgG and lysozyme            Concentration of protein with protein assay kit (Lowry, BCA and Bradford)

Cell Culture:Concentration of suspended cell cultures

UV-VIS:     UV/VIS full-spectrum (200~850nm) absorbance scan

Microarray:Concentration of fluorescent dye labeled nucleic acid (microarray),  for it can measure the concentration of the nucleic acid and the dye at the same time

General operation

1 Drop directly 0.3~2µL sample onto the test platform with a pipette.

2 Close the sampling arm.

3 Click the “Measure” button, and the result(values and graph) of the sample will appear in seconds.

4 Wipe the sample from the test platform with clear absorbent paper.

5 Click the “Save Graphic” button after measured a sample if you want to save the graph.

6 Click the “Show Report” button after the samples measured to output the result data of the samples by excel.
