Hydroquinone (C6H6O2), chloroauric acid (AuCl4H), trisodium citrate dihydrate (C6H5Na3O7), and PEG 20000 were bought from Macklin (Shanghai, China). The NC membrane, sample pad, conjugated pad, polyvinylchloride (PVC) backing card, and absorbance pad were purchased from Jieyi Biotechnology Co., Ltd. (Shanghai, China). Latex microspheres were purchased from Bans Laboratories, Inc. (Indiana, United States). TTX (≥95% pure) was purchased from CATO Research Chemicals Inc. (Guangzhou, China), and anti-TTX-monoclonal antibodies (anti-TTX mAb) from hybridoma cell 5B9 were produced by us and stored in our lab (Ling et al., 2015 (link)). Anti-TTX mAb had no cross-reactivity against saxitoxin acetate (STX), conotoxin (CTX), brevetoxin (BTX), pectenotoxin (PTX), and microcystin (MC) (Ling et al., 2015 (link)). μ-Conotoxin KIIIA (μ-CTX KIIIA), αB-conotoxin VxXXIVA (αB-VxXXIVA-CTX), APETx_2 (κ-actitoxin-Ael2a, UniProt P61541), BDS-I (∆κ-actitoxin-Avd4a, UniProt P11494), and sea snake neurotoxins-311 (SN311) (≥85% pure) were prepared by Sangon Biotech (Shanghai) Co., Ltd. OA (≥98% pure) was purchased from Sigma-Aldrich (St, Louis, MO, United States).

Ferric nitrate nonahydrate (Fe(NO3)3·9H2O), glycerol, isopropyl alcohol, absolute ethanol, polyethylene glycol (PEG 20000), nitric acid (HNO3), sulfuric acid (H2SO4), potassium permanganate (KMnO4), hydrogen peroxide (H2O2), sulphur powder and graphite powder were bought from Macklin. Lithium iodide (LiI), lithium perchlorate (LiClO4) and tetrabutyl ammonium iodide, 4-tert-butyl pyridine, acetonitrile, were obtained from Aladdin. All the chemical-grade agents were commercially purchased without further purification.

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.
