Polyand DNA transfection reagents
Choose Virus or Protein for the intended output. Match the product to cells, culture mode and output assessment; protein-expression data retain their original experimental scope.

Product selection
Choose Virus for AAV/lentiviral-vector production and Protein for protein/antibody expression in 293/CHO systems. Assess output, cell state and function separately, using the corresponding product instructions for ratios and timing.

Polyand Protein expression example
The original brochure compares protein yield in CHO and 293 cells across complex incubation times. This evidence belongs to the Protein product and is not a Virus-product performance claim.
Application data
Protein-expression example in CHO and 293 cells
Polyand for Protein DNA Transfection Reagent, Cat. No. 100006-2. The original brochure compares protein yield in CHO and 293 cells across complex incubation times; this is an application example, not a release specification.
- Cells: CHO and 293
- Readout: protein yield, mg/L
- The source does not specify the expression construct, DNA input, culture scale or harvest time.
Samples and output evaluation
Separate Virus and Protein by intended output
The Qihe brochure positions Virus for AAV/lentiviral-vector production and Protein for protein/antibody expression in 293/CHO systems. They have different output-assessment endpoints.
- For Virus, specify vector type, production cells, suspension or adherent culture and intended yield/function metrics, then establish conditions from the corresponding product instructions.
- For Protein, specify the expression construct, host and target protein. Assess cell state, recovered yield and target function rather than transient fluorescence alone.
Record conditions for scale transfer
The brochure shows expression and complex-stability examples in specific systems, not one universal recipe for all cells and culture modes.
- Record cells, DNA quality, culture system, actual complex preparation/holding time and sampling endpoint, using comparable assessment criteria.
- Confirm working ratios, addition and harvest conditions in the selected Virus or Protein instructions. Protein CHO/293 data illustrate that product and do not validate Virus performance.

Frequently asked questions
How should I choose between Polyand Virus and Protein?
Choose by output: Virus addresses AAV/lentiviral-vector production; Protein addresses protein and antibody expression in 293/CHO systems. Provide host, suspension/adherent culture and assessment endpoints, then establish suitability from the corresponding product information.
Do the Protein CHO/293 figures establish Virus production performance?
The figures are specific protein-expression examples for the Protein product and do not validate Virus. Assess yield and required function separately for each intended output, retaining the original cell and processing context.
Does stronger transient fluorescence guarantee greater final output?
Also assess cell state, recovered yield and target-product function. Reporter signal, harvested protein titer and vector function are different endpoints; compare using measures appropriate to the intended output.
Can fixed ratios and timing be reused after changing cells, culture mode or scale?
A brochure example does not establish a universal recipe. Record cells, DNA quality, culture system, complex preparation/holding time and sampling endpoint. Confirm conditions in the corresponding instructions and assess scale transfer from comparable small-scale results.
