Wholesale Distributors for Soluble Lyophilized Silk Fibroin to Qatar Importers Detail:
Brand Name: Fancci
Alternative Name: Freeze-dried silk fibroin
Introduction:
Large molecular weight silk fibroin in aqueous solution can be processed into different solid material formats. Unfortunately, the purified silk solution can’t be stored or transported for a long time as silk undergoes structural changes and aggregates due to thermodynamic instability. Our proprietary lyophilized silk product completely solve these problems and the lyophilized silk can be dissolved in water or buffer at high concentration, facilitating downstream material processing.
Lyophilized silk in a glass vial presents to be a white porous sponge. Since the vial is completely sealed, lyophilized silk can remain stable for a long period of time (> 18 months) at room temperature in terms of appearance, solubility, molecular weight distribution and structure. The regenerated silk solution remains the same structural transition capability from random coil andα-helix structure to β-sheet structure as original silk solution, which is critical in preparation of solid material formats.
Table 1 Parameter, testing and method of lyophilized silk fibroin
Parameter, Testing and Method | Lyophilized Silk Fibroin |
Category | Materials/Agents |
Form | Lyophilized agents |
Source | Degummed Bombyx mori silkworm |
Package | 20 ML Penicillin Bottles |
Method of storage | Stored in a dry, ventilated place at room temperature |
Solution concentration after rehydration | ≤ 40% |
Bioburden | Sterilized |
Molecular Weight | ≥200,000 Da |
Expiration Date | 18 months |
Operation method:
Lyophilized silk fibroin can be stored at room temperature for 18 months. Before use, water or buffer or cell/drug solution can be added into the sterile glass bottle using a needle syringe (keep sealed) or a pipette (open bottle). The lyophilized silk cake in the bottle can be quickly rehydrated forming a light yellow solution and the silk concentrations obtained can reach up to 30-40%.
Application:
Same as the solution after purification, the soluble lyophilized silk fibroin can also be used as a basic raw material for fabrication of many biomedical products. Furthermore, soluble lyophilized silk fibroin has advantages of longer and ambient storage, easier transportation and higher concentration of regenerated solution compare to regular silk fibroin solution.

The Solu-Sert™ filter capsule is a self-contained filter “cassette capsule” that captures all particles collected by a filter cassette. It consists of an MCE filter membrane sealed to a cellulose shell to create the capsule. This capsule is then inserted into a Zefon 2-Piece filter cassette with a support pad as a complete unit. After sampling the entire capsule is removed, digested in an acid solution, and then analysis performed. This process eliminates the need to rinse or wipe the cassette interior to account for “wall deposits” and makes it ideal for performing airborne metals analysis
Why, and just how do facial revival exercises work? Once you begin a first-rate facial workout process, the muscles on the face and throat skin start building fiber.

The tissue oxygenates and fills, and the connective tissue linking the skin, muscle, and bone gets elastic and elevates. This leads to hanging jowls lifting, facial imperfections and small veins decreasing. The eyes appear more open, the eyebrows lift up, the jaw and cheekbones become honed and shapely, and you get a youthful looking skin that has a new, revitalized glow.

This overall improvement produced with facial manipulation workouts result in the inevitable non-surgical facelift you rightly deserve. Your entire complexion looks radiant as the blood flow increases to the epidermis of the face and neck. The pores of the skin become more open and receptive to moisturizing, too. Facial acupressure aerobics discloses how to task your fingers to erase years off your appearance!
Wendy Wilken’s face toning program known as Face Engineering Exercises affords guys and women a wonderful opportunity to appear more youthful, employing facial toning, and also facial acupressure techniques. Because Wendy’s face exercise program is performed on nodal zones and energy lines on the face and throat, the benefits of the face restoration aerobics are increased threefold. Way better than just face training aerobics on their own!
No other face workout program on this planet employs facial acupressure treatments except Wendy Wilken’s facial yoga system known as Face Engineering Exercises. This makes it better than other face aerobics programs which exploit only isometrics (skin stretching) or peculiar face pulling workouts. Wendy’s Face Engineering Exercises method doesn’t apply these regimens.
The Face Engineering Exercises facial tissue strengthening and wrinkle removal solution stimulates the underlying tissue instead of the skin itself. This builds and expands the delicate muscles on the face which then draws the skin towards the muscles, hence refining your looks within days and weeks. Now combine face toning exercises on acupressure energy points, and the age-reversing effects are fast-forwarded and the results boosted for wonderful looks.
Only twenty facial rubbing gymnastics are needed to generate huge improvements to the face and restore your youth. It takes about 3 days to learn these facial manipulation aerobics and you will know them by heart without referring to the face training regime any more. So straightforward! Yet so effective for reversing the aging problem.
