Message: | Disposable virus sampling tube: (sampling swab + virus storage tube + virus preservation solution)
Sampling swab: the sampling swab directly contacts the sampling part, and the material of the sampling head is closely related to the subsequent detection. The sampling swab head should be made of polyester (PE) synthetic fiber or rayon (artificial fiber), calcium alginate sponge or stick swab (including bamboo swab) cannot be used. The material of swab head cannot be cotton product, because the fiber of cotton has strong adsorption on protein and is not easy to elute into the subsequent preservation solution; however, the stick or bamboo stick containing calcium alginate and wood components is soaked after breaking The bubble also adsorbs protein in the preservation solution, and even inhibits the subsequent PCR reaction.
Virus preservation tube: it is mainly to prevent leakage, can we find such a storage tube? When tightening, tighten until tight; when loosening, loosen once. The answer is yes. Desheng's disposable virus sampling pipe cover spin thread, and it is easy to screw.
Virus preservation solution: there are two kinds of virus preservation solution: inactivation and non inactivation. |
