Slide-Fix™ PAP Jar — Yellow Cap Applications
The yellow-capped Slide-Fix™ PAP jar is compatible with the following histology, cytology, and molecular pathology slide staining workflows.
| Application | Setting / Configuration | Notes |
|---|---|---|
| Chromogenic substrate (AEC/DAB) | IHC chromogenic detection, substrate jar | Yellow: bright ID for chromogenic substrate jar |
| H&E eosin | Histology bench, eosin immersion | Yellow for eosin when orange is used for another step |
| Enzyme substrate | AP or HRP substrate solution | Yellow: substrate identification in enzyme-based detection |
| Final rinse / aqueous mount | Post-stain rinse before coverslipping | Yellow cap for final rinse jar in H&E or special stain run |
| Trichrome reagent | Masson's trichrome, Bouin's fixative | Yellow: distinctive for complex multi-color stain protocols |
| Gram stain iodine | Microbiology, Gram stain, iodine step | Yellow cap matches iodine solution visual cue |
| FISH mounting medium | Anti-fade mounting solution | Yellow for mounting medium jar in FISH protocol |

| Ethanol (70–100%) | Excellent | PPC compatible with full dehydration ethanol series. |
| Xylene substitutes | Excellent | PPC compatible with standard xylene substitutes. |
| Hematoxylin / eosin | Excellent | H&E staining reagents fully compatible. |
| Methanol / isopropanol | Excellent | PPC: full methanol compatibility. |
| IHC antibodies / buffers | Excellent | PBS, TBS, antibody diluent all compatible. |

| Concentrated H2SO4 / NaOH | Limited | Avoid concentrated acids or bases. |
Clinical & Research Laboratory Applications
Caplugs® Evergreen Slide-Fix™ PAP jars with yellow caps serve IHC, chromogenic detection, and special stain laboratories requiring a bright, high-visibility cap for substrate or enzyme reagent jars. Yellow is the conventional color association for chromogenic substrates (DAB appears brown; AEC appears red — but their substrate solutions are often lightly colored or colorless, making yellow cap identification practical). In Gram staining, yellow caps logically mark the Lugol's iodine jar, matching the iodine solution's own amber-yellow color. For multi-step special stain protocols (Masson's trichrome, PAS), yellow differentiates from the saturated orange and green caps used for other steps in the same run.

Frequently Asked Questions
Are the Slide-Fix™ PAP jars sterile?
Yes. Sterile — packed 10/Bag Assembled.
What is the complete Slide-Fix™ PAP jar color set?
Eight colors: Natural (222-5450-08S), Blue (222-5450-B8S), Orange (222-5450-E8S), Green (222-5450-G8S), Fuschia (222-5450-K8S), Lavender (222-5450-L8S), Red (222-5450-R8S), Yellow . All are identical PPC jars at the same price — only the cap color differs.
Is there a standard color convention for Slide-Fix™ PAP jar reagent assignment?
There is no universal mandated convention — each laboratory assigns reagents to cap colors per their own SOP. Common practices include: Red/Orange for fixatives or hazardous reagents; Blue for wash buffers; Lavender for antibody solutions; Yellow for substrates; Natural for neutral or final rinse solutions. The eight-color set allows each lab to establish and document their own color-coding scheme that fits their specific staining protocols.
