生物活性

Brilliant black BN (E151) is an azo dye and a food colorant[1]. Brilliant black BN is a promising antiviral agent against EV71 infection via inhibiting the interaction between EV71 and its cellular uncoating factor cyclophilin A. Brilliant black BN has the potential for the investigation of contagious disease[2].

IC50 Target

IC50: 2.39 µM- 28.12 µM (various strains of EV71)[2]

体外研究
(In Vitro)

Brilliant black BN (E151) inhibits the interaction between EV71 and its cellular uncoating factor cyclophilin A [1].
Brilliant black BN (E151) inhibited the infection EV71 -GFP at a concentration of 300 µM as evidenced from the reduced GFP signals. Brilliant black BN (E151)exhibits the inhibition of EV71 -GFP as a dose-dependent manner in infected RD cells, exhibits an IC50 value of 10.1 µM[1].
Brilliant black BN (E151) is able to inhibit all tested 28 EV71, CVA16 and CVA6 strains. In rhabdomyosarcoma cells, 50% inhibitory concentration 29 of the dye E151 for various strains of EV71 ranged from 2.39 µM to 28.12 µM ,whereas its 50% cytotoxic concentration is 1870 µM [1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

体内研究
(In Vivo)

Brilliant black BN (E151)(intraperitoneal injection; 200 mg/kg; 14 days)exhibits mild illness with clinical scores less than 3 and subsequently recovered when compared with PBS-group.All E151 270 treated mice are completely protected throughout the experiment[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: 14-days old AG129 mice with EV71[1]
Dosage: 200 mg/kg
Administration: Intraperitoneal injection
Result: Had a Protective eddect on EV71 challenged AG129 mice by dye E151.

生物活性

Hematoxylin (Natural Black 1), a naturally occurring flavonoid compound derived from the logwood tree, Haematoxylon campechianum. Hematoxylin is a nuclear stain in histology and is also a potent Aβ42 fibrillogenesis inhibitor with an IC50 of 1.6 µM.

IC50 Target

IC50: 1.6 µM (Aβ42 fibrillogenesis)[2]

体外研究
(In Vitro)

When exposed to air, Hematoxylin is oxidized to reddish brown hematein. When oxidized to its hematein form and combined with a mordant, usually a metal salt, Hematoxylin stains tissue sections a deep blue to black color depending on the staining method. By itself, Hematoxylin is also amphoteric in its hematein form; it is red at acid pH and blue at alkaline pH. Differentiation following Hematoxylin staining removes nonspecific staining[1].
Hematoxylin treatment greatly alleviates Aβ42-induced cytotoxicity in SH-SY5Y cells. Hematoxylin is a potential agent against Aβ fibrillogenesis and cytotoxicity[2].
The Hematoxylin and Eosin (HE) stained tissue section is the cornerstone of anatomical pathology diagnosis. The HE procedure stains the nucleus and cytoplasm contrasting colors to readily differentiate cellular components[3].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Guidelines (Following is our recommended protocol. This protocol only provides a guideline, and should be modified according to your specific needs).
The method of HE staining[4]:
1. Place the glass slides that hold the paraffin sections in staining racks. Clear the paraffin from the samples in three changes of xylene for 2 min per change.
2. Hydrate the samples as follows.
i. Transfer the slides through three changes of 100% ethanol for 2 min per change.
ii. Transfer to 95% ethanol for 2 min.
iii. Transfer to 70% ethanol for 2 min.
iv. Rinse the slides in running tap water at room temperature for at least 2 min.
3. Stain the samples in Hematoxylin solution for 3 min.
4. Place the slides under running tap water at room temperature for at least 5 min.
5. Stain the samples in working eosin Y solution for 2 min.
6. Dehydrate the samples as follows.
i. Dip the slides in 95% ethanol about 20 times.
ii. Transfer to 95% ethanol for 2 min.
iii. Transfer through two changes of 100% ethanol for 2 min per change.
7. Clear the samples in three changes of xylene for 2 min per change.
8. Place a drop of Permount over the tissue on each slide and add a coverslip. View the slides using a microscope.

Sudan Black B, a fat-soluble diazo dye, is a histochemical stain. Sudan Black B can be used for staining of neutral triglycerides and lipids[1].

体外研究
(In Vitro)

Sudan Black B works also in frozen material, and therefore can be complementarily used with SA-β-gal when investigating senescence. Sudan Black B is a highly lipophilic agent that exhibits high affi nity to the lipid compartment of lipofuscin. The positive Sudan Black B-lipofuscin reaction reveals blue-black intracellular granules in cells and frozen tissues and brown to black granules in FFPE tissues under the light microscope.
