  • Supplier: Log in to see
  • Lot number: D05923BA
Controls
  • Tissues stained came from a human formalin-fixed paraffin embedded (FFPE) tissue microarray (12-003d):
  • Positive control (specimen known to contain the target protein): human testis, which is expected to express high levels of the antigen.
  • Negative Control (specimen known to not contain the target protein): Indeterminate; protein located on cytoplasmic membrane surface of intercellular tight junctions. The protein may be involved in signal transduction at cell-cell junctions. Expression is expected to be widespread. Thymus, expected to express much lower levels of the antigen as compared to testis, is shown to demonstrate a tissue with no detectable expression.
  • Primary antibody isotype control: Testis (specimen known to contain the target protein) treated with primary antibody isotype control instead of the primary antibody.
  • Secondary antibody only control: Testis (specimen known to contain the target protein) treated with secondary antibody only (no primary antibody).
实验流程

Experimental Notes
  • Deviations from protocol/procedure supplied by manufacturer (attached).
  • Step 1: Heated tissue 60°C for 30 minutes; manufacturer heats for 45 minutes.
  • Step 2: No ethanol wash was performed during deparaffinization; manufacturer includes 1 wash of 80% ethanol for 3 minutes.
  • Step 3.1: Slides were heated for 15 minutes; manufacturer provides a range of 15-20 minutes.
  • Step 3.2: Slides were cooled for 30 minutes; manufacturer cools for 20 minutes.
  • Step 4: Italicized reagents and incubation time are fixed instrument parameters.
  • Step 5: Secondary species-specific serum block not used; manufacturer blocks with 5% normal goat serum for 2 hours.
  • Step 8.1: Antibody diluted in PBS at 1:250; manufacture did not recommend diluent or dilution.
  • Step 8.2.1: Primary antibody incubated at room temperature overnight; manufacturer incubates overnight 4°C with agitation.
  • Tissue Interpretation (limited): - TJP1: Under the staining parameters described above, testis stained weakly (ducts) positive (Figure 1). Substantial signal detected in limited number of other tissues, including: breast, normal (NOS); pancreatic cancer (NOS), and stomach, normal (NOS). Most tissues showed low level of specific signal. Thymus did not have any detectable signal (Figure 4).
  • I-NC (Isotype negative control): No signal detected
  • B-NC (Blank negative control): No signal detected
  • Signal Localization: - Signal to noise was adequate with cytoplasmic, nuclear subcellular localization observed. Rare inner-membrane and no distinct membrane signal observed.

别名 Zo-1 (TJP1 Antibody 摘要)
背景

The N-terminal may be involved in transducing a signal required for tight junction assembly, while the C-terminal may have specific properties of tight junctions. The alpha domain might be involved in stabilizing junctions. Plays a role in the regulation of cell migration by targeting CDC42BPB to the leading edge of migrating cells.

Subcellular location: Cytoplasm

Synonyms: ZO-1, Tight junction protein ZO-1, Tight junction protein 1, Zona occludens protein 1, Zonula occludens protein 1, TJP1, ZO1
