Sericin
Based on 1 Customer Validation
Sericin is an orally active globular protein produced by silkworm cocoons. Sericin inhibits the expression of COX2, iNOS, TLR4, MAPK and NF-κB; reduces the levels of IL-18, IL-1 and CCL2; antagonizes the activity of AChE; and downregulates the expression of Bcl-2. Sericin enhances the PI3K/AKT-mediated insulin signaling pathway. Sericin inhibits the activity of tyrosinase (Tyrosinase), scavenges ROS, chelates metal ions, and increases the levels of antioxidant enzymes. Sericin induces apoptosis and arrests the cell cycle. Sericin exhibits antibacterial, moisturizing, cardioprotective and anticoagulant properties. Sericin can be used in research related to type 2 diabetes, hyperlipidemia, obesity, Alzheimer's disease, colon cancer, peripheral nerve injury and ischemic myocardial infarction.

Sericin promotes the production of TNF-α and IL-1β in monocytes and alveolar macrophage cell lines without activating other inflammatory cascades[1].
Sericin reduces the expression of c-fos, c-myc and COX-2 in normal epidermal cells stimulated by TPA (HY-18739), thereby exerting anti-inflammatory effects[1].
Sericin exhibits anticancer activity by inducing apoptosis and S-phase cell cycle arrest in SW480 colon cancer cells, which is achieved by enhancing Caspase-3 activity and reducing Bcl-2 expression[1].
Sericin acts as an efficient substitute for bovine serum albumin, and promotes the proliferation of hybridoma cells 2E3-O, HepG2, HeLa, 293, Balb3T3 and RC4 corneal cells in serum-free medium[2].
0.5% Sericin increases the blastocyst development rate of prepubertal lamb oocytes cultured in vitro, and when combined with FLI, their developmental capacity reaches a level comparable to that of adult follicular fluid[2].
Sericin (80 µg/mL) enhances the amplification of ZIKV in C6/36 insect cells and Vero mammalian cells in vitro, while also providing cryoprotection for C6/36 cells[2].

Sericin (p.o.) reduces blood glucose levels, improves insulin sensitivity, and enhances antioxidative activity in type 2 diabetic mice[2].
Sericin treatment improves cardiac mitochondrial structure, metabolism, and protein expression profiles in hypercholesterolaemic rats[2].

Solvent & Solubility
DMSO : 25 mg/mL (ultrasonic and warming and heat to 60°C; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL; Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL; Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

The co-solvents required include: DMSO, . All of co-solvents are available by MedChemExpress (MCE). , Tween 80. All of co-solvents are available by MedChemExpress (MCE).
Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .
μL , mix evenly;
3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
