Anmerkungen:

• 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.

Details zu TJP1

Target: TJP1 (Tight Junction Protein 1 (TJP1))

Andere Bezeichnung: ZO-1 (TJP1 Produkte)

Synonyme: ZO-1 antikoerper, ZO1 antikoerper, zo1 antikoerper, tight junction protein 1 antikoerper, tight junction protein ZO-1 antikoerper, TJP1 antikoerper, Tjp1 antikoerper, LOC396567 antikoerper

Hintergrund:

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

Background: 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.
