高效价甘薯羽状斑驳病毒抗血清的制备

  • 用嫁接方法将甘薯羽状斑驳病毒(SPFMV)接种到I.setosa上扩繁,以0.2mol/LpH7.2PBK缓冲液、垫层差速离心、蔗糖密度梯度离心提取纯化SPFMV。纯化的SPFMVOD260/280的比值为1.25。将纯化的SPFMV免疫家兔制备抗血清,在环状沉淀和微量沉淀试验中,用提纯病毒测定抗血清的效价均为1:4096;以SPFMV-IgG为第一抗体,应用Dot-ELISA对甘薯和I.selosa叶片中的SPFMV分别作了测定。

Preparation of High Titer Antiserum to Swee!Potato Feathery Mottle Virus(SPFMV)

  • weet potato feathery mottle virus(SPFMV)was inoculated to I.selosa to propagare by graftingand was purified wirh 0.2mol/L pH7.2 PBK.Further purification of SPFMV was conducted by sucrose cushion and sucrose density gradient centrifugation.Purified SPFMV had a OD260/280 ratio of1.25.Rilbbit was immuned with purifled viruses to prepare antiSerum.Antisera produced to purifiedvirus had a titer of 1:1096 in microprecipitin and ring precipitin tests.SPFMV in leaves of sweet potato and I.selosa were detected respectively by indirect enzyme-linked immunosorbent assay(ELISA)onnitreeellulose membranes.

    Preparation of High Titer Antiserum to Swee!Potato Feathery Mottle Virus(SPFMV)

    • 1. Biology  

    Abstract: weet potato feathery mottle virus(SPFMV)was inoculated to I.selosa to propagare by graftingand was purified wirh 0.2mol/L pH7.2 PBK.Further purification of SPFMV was conducted by sucrose cushion and sucrose density gradient centrifugation.Purified SPFMV had a OD260/280 ratio of1.25.Rilbbit was immuned with purifled viruses to prepare antiSerum.Antisera produced to purifiedvirus had a titer of 1:1096 in microprecipitin and ring precipitin tests.SPFMV in leaves of sweet potato and I.selosa were detected respectively by indirect enzyme-linked immunosorbent assay(ELISA)onnitreeellulose membranes.
