The company’s whitepaper and the project’s website are written in Chinese, not English. Although its Twitter profile is in English, CVNT hasn’t posted anything there for well over a year. While CVNT could have a lot bigger following in China, it doesn’t bode well for a prominent crypto project looking for international attention to not have an English-translated whitepaper and website. Of the total possible supply of 1,000,000,000 CVNT, the current circulating amount is -.

The cVNT and pVNT platforms remain the only platforms for detection of NAbs. However, both require live viruses and cells, highly skilled operators, and days to obtain results. They are thus not suitable for mass production and testing on a commercial scale, even in the most developed nations. Statistical analysis was performed using GraphPad Prism 7 software.

The differences between negative control and COVID-19 test sera were analyzed using an unpaired t-test. The differences between paired SARS serum in SARS-CoV-2 sVNT and SARS-CoV sVNT were analyzed using a paired t-test. Correlations between sVNT and cVNT or pVNT were analyzed using Pearson correlation coefficients.

Mainstream crypto exchanges like Coinbase aren’t going to carry CVNT. Your best bet would be to check out dedicated altcoins exchanges like Binance, Bittrex, and Bitmax. Keep in mind that with a market cap of only $8.8 million, there’s very little liquidity on the market. It will be almost impossible to buy or sell large investments in CVNT. Putting all this aside, the fact that CVNT’s popularity has remained unchanged over the past few months, despite the surge in popularity for Bitcoin and other altcoins, is also a warning sign for investors. If CVNT can’t grab any attention from crypto investors, that’s probably a red flag that the project is doomed to obscurity or failure.

To validate the performance of the SARS-CoV-2 sVNT, we tested two different cohorts of positive and negative sera. The assay was performed in two different countries by two independent groups to further ensure reliability and reproducibility. A cutoff at 30% inhibition was chosen from testing over 500 negative human sera. For the first cohort, we tested 175 sera from patients with PCR-confirmed COVID-19 in Singapore collected on days 14–33 after symptom onset and 200 healthy control sera, resulting in 100% specificity and sensitivity of 98.9% (Fig. 4d). For the second cohort, we tested 50 sera from patients with PCR-confirmed COVID-19 in Nanjing, China, sampled on days 27–61 after symptom onset and 200 healthy control sera.

The Conscious Value Network price page is just one in Price Index that features price history, price ticker, market cap, and live charts for the top cryptocurrencies. Conscious Value Network’s price today is US$0.5964, with a 24-hour trading volume of $26,306. CVNT is +0.00% in the last 24 hours.CVNT has a max supply of 1 B CVNT.

The altcoin market’s popularity has been exploding over the past few months. While that’s good news for most tokens, there are some obscure coins that are hardly getting any traction whatsoever. The Content Value Network Token (CVNT) is one altcoin that isn’t getting any coverage right now, and there are a few reasons why.

All other assays, such as enzyme-linked immunosorbent assay (ELISA) and lateral flow assay (LFA) rapid tests, represent the second assay type, which detects total binding antibodies (BAbs) and is unable to differentiate between BAbs and NAbs6,9,10. The data presented here demonstrated that sVNT is as specific as, but more sensitive than, cVNT in the cell types tested here (Fig. 4). In our initial optimization studies, we found that the RBD protein performed better than the S1 protein (Extended Data Fig. 1).

SARS-CoV-2 specific antibody and neutralization assays reveal the wide range of the humoral immune response to virus

First, most, if not all, testing currently performed at the large scale is for detection of BAbs alone and does not measure true NAbs; second, the presence of NAbs may or may not correlate with protection. In this study, we have developed a serological platform to tackle the first technical challenge. A panel of 60 COVID-19 sera with different levels of SARS-CoV-2 NAbs content value network cvnt first determined by sVNT were chosen for a comparative and correlation study between sVNT and two other VNTs, cVNT and pVNT. 4a–c, all three VNT assays had a good overall correlation, with sVNT–cVNT correlating slightly better than sVNT–pVNT or pVNT–cVNT. The sVNT titer was calculated using the half-maximum inhibitory concentration (IC50; Supplementary Table 2).

A patent application has been filed for the content disclosed in this study and a SARS-CoV-2 sVNT kit is in the process of commercialization with industrial partners.

It can also be used to assess vaccine efficacy during preclinical and clinical trials of different vaccine candidates and to monitor neutralizing titers in vaccinees after mass vaccination in human populations. Another advantage of sVNT is its ability to detect SARS-CoV-2 antibodies in a species-independent manner. Sampling serum for antibody detection is also more reliable than other sampling approaches used for molecular detection, as the target tissues can vary from virus to virus25,26,27.

In our study, direct binding was demonstrated using different SARS-CoV-2 proteins conjugated with horseradish peroxidase (HRP). There is a dose-dependent specific binding between hACE2 and the RBD or S1, but not the nucleocapsid (N) protein, with the RBD producing the best binding characteristics (Fig. 1c). We then demonstrated that the specific RBD–hACE2 binding can be blocked or neutralized by COVID-19 sera in a dose-dependent manner, but not by sera from healthy controls (Fig. 1d). Using a panel of 20 convalescent sera, we demonstrated that HRP–RBD performed better in detecting NAbs than HRP–S1 (Extended Data Fig. 1).

To demonstrate specificity, we tested different panels and confirmed that the SARS-CoV-2 sVNT can differentiate antibody responses to SARS-CoV-2 from those to other human CoV infections (Fig. 3c). For human sera from patients with 229/NL63 or OC43 infection and alpaca sera from experimental MERS-CoV infection, there is no detectable cross-neutralization. For SARS sera, there is some level of cross-reactivity, not unexpected given their close genetic relatedness and what was reported previously3,7.
