N peptide pools

Manufactured by Miltenyi Biotec

N-peptide pools are collections of synthetic peptides derived from known protein sequences. These peptide pools are designed to facilitate the identification and analysis of immune responses, such as T-cell epitope mapping. The core function of N-peptide pools is to provide a comprehensive set of peptides that can be used as tools for various immunological and biological research applications.

ELISPOT was performed according to the manufacturer’s instructions (Cellular Technology Ltd.; MU IFN-γ). Plates were coated with anti–IFN-γ capture antibody (Cellular Technology Ltd.) at 4°C overnight. Splenocytes (0.25 × 106) were stimulated in duplicates with SARS-CoV-2 S-peptide (2 μg/ml; Miltenyi Biotec, 130–126-701) or N-peptide pools (2 μg/ml; Miltenyi Biotec, 130–126-699) for 24 hours at 37°C. Splenocytes stimulated with anti-CD3 (1 μg/ml; Thermo Fisher Scientific, 16–0031-82) or medium alone were used as positive and negative control, respectively. This was followed by incubation with biotin-conjugated anti–IFN-γ (Cellular Technology Ltd.) for 2 hours at room temperature and then alkaline phosphatase–conjugated streptavidin for 30 min. The plates were washed and scanned using an ImmunoSpot 4.0 analyzer, and the spots were counted with ImmunoSpot software (Cellular Technology Ltd.) to determine SFC per 106 splenocytes.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
