Overview

  • Product name

    Anti-NSP1 antibody [32D6]

  • Description

    Mouse monoclonal [32D6] to NSP1

  • Host species

    Mouse

  • Specificity

    This antibody was initially identified as directed against a nuclear pore complex antigen by immunofluorescence localization. A screen of a lgt11 expression library yielded a single positive clone carrying an insert bearing ~66% of the C-terminal portion of NSP1. To confirm that 32D6 possessed high affinity for NSP1, strain RS453, which expresses a shortened isoform of NSP1, was compared to the wildtype strain BJ5465. NSP1 in RS453 contains an internal deletion that removes the coding sequence for 6 FXFG repeats, which are not essential for function and encodes a protein that has been observed to migrate at approxmately 85 kDa on SDS gels. The predicted size of wildtype NSP1 is 86.5 kDa, but NSP1 has been observed to migrate on SDS gels at ~100 kDa. In our gels, the apparent molecular mass of wildtype NSP1 was 108 kDa, whereas the short isoform of NSP1 in RS453 migrated at 91 kDa. The detection of two protein bands of apparent sizes 108 kDa and 91 kDa in BJ5465 and RS453, respectively, demonstrated that 32D6 recognized the pore complex protein NSP1.

Target

  • Relevance

    NSP1 functions as a component of the nuclear pore complex (NPC). It plays an important role in several nuclear transport pathways including poly(A)+ RNA, tRNA, pre-ribosome, signal recognition particle (SRP), and protein transport.

  • Cellular localization

    Nuclear membrane: part of the nuclear pore complex, it presents a symmetric distribution with a cytoplasmic and a nucleoplasmic side.

    Answer

    Thank you for your enquiry. I have contacted the source of the three antibodies and as such unfortunately I cannot give you an exact figure on the protein or IgG concentration of the antibodies. However, all three are derived from tissue culture supernatants and are therefore in the range of 0.5mgml-1 to 1.0mgml-1. Please do not hesitate to contact me should you require further assistance.
