冻干粉溶解过程500

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.

  • Soil texture is the description of the composition of the soil in relation to sand, silt and clay. Sand being the coarsest fraction and clay being the finest fraction.

    The soil texturing is one of the most important assessments you can conduct on your soil as is allows you to relate general soil properties such as
    • Soil water infiltration, retention and plant availabliity
    • Soil structure- development and stability
    • Nutrient retention and plant availablilty
    • Erodibility to wind and water
    • Drainage characteristics

    There are two ways to determine soil texture.

    The first is to send a soil sample away to an accredited laboratory for a Soil particle analysis to determine the exact sand silt and clay proportions.

    The second is the hand texturing, which Central West Local Land Services Croppnig Officer Neroli Brennan demonstrates in this video.

    METHOD

    1. Take a handful of soil (remove anything larger than 2mm), and if dry, add water until soil comes together to form a ball.

    2. Knead the soil between your thumb and your forefinger ensuring that the soil is completely mixed and no large lumps are present, this should take 1-3min.

    3. By pushing the soil between the thumb and forefinger you should be able to form a ribbon of soil which will allow you to feel the soil constituents and the length of the ribbon helps in assessing the clay content of the soil.

    SAND – feels gritty and hard to the touch, held to the ear you can also hear the sand

    SILT – feels smooth, silky, even soapy but with little stickiness

    CLAY – feels smooth and sticky

    Once you are aware of the soil texture you are managing it will help you to decide what types of enterprises or activities your soil is suited to, the types of plants you can grow and the management issues you need to monitor for long term production.
