Adult LacZ Expression Data for Fam107b (MBNT)

Overview

Adult expression (≥ 6 weeks): The lacZ reporter gene within the targeting vector was used to determine the wholemount expression profile of the targeted gene. Mice were fixed by cardiac perfusion using 4% paraformaldehyde (PFA). Following dissection, the tissues to be stained were fixed an additional 30 min in 4% PFA before being rinsed in phosphate buffered saline and transferred to lacZ staining solution, containing 0.1% X-gal, for up to 48 hours. After an additional overnight post-staining fixation in 4% PFA, tissues were cleared with 50% glycerol then transferred to 70% glycerol for long-term storage.

Display Criteria

A tick-list of 41 tissues and organs was scored for the presence (green tick) or absence (red cross) of lacZ expression.

  • The term 'Ambiguous' was assigned when there was uncertainty as to the validity of the observed pattern e.g. staining may be very faint, background or an artefact due to trapping.
  • The term 'No Data' was assigned if the stained entity was not available to assess.

By default, up to 27 standard images may be taken using a Leica MZ16A microscope and Imagic software. These images were only collected when X-gal staining was present.

Background LacZ Staining in Adult

The adult wholemount LacZ expression protocol has been refined to minimize background staining however, it can still occur. We have systematically documented the sites and intensities of this background stain in male and female wildtype C57BL/6 (C57BL/6J-Tyr<c-Brd>; C57BL/6NTac/Den) mice. The major locations where background staining may be observed are:

  • Nasal cavity
  • Thyroid gland
  • Glandular stomach
  • Kidney
  • Male genitals

Additional background staining is observed occasionally in:

  • Rib cage
  • Thymus
  • Mesenteric lymph nodes
  • Ovaries
