Media Salts and Chemicals
Description
Cell Applications Media Salts and Chemicals are suitable for cell culture and test negative for bacteria, yeast and fungi. The products are sterile and ready-to-use, with the exception of the AAS solution which is diluted 100X for use.
- Antibiotic Antimycotic Solution (AAS) is used to control bacterial and fungal contamination in culture medi.
- Hank’s Balanced Salt Solution (HBSS) maintains pH and osmotic balance, provides cells with water and essential inorganic ions, and washes cells before Trypsin/EDTA treatment during subculture. HBSS is designed for use with cells maintained in non-CO2 atmospheric conditions.
- L-Glutamine Is an essential amino acid supplement and energy source for cell culture media, important for cell growth, division & function, protein & amino acid synthesis.
- Phenol Red, typically used at 11 mg/L, is used widely in culture media to identify changes from neutral to acidic pH values, the latter signifying contamination or cell over-growth. It imparts an increasingly yellow color as pH drops below 6.4, and a deepening red color at a pH of 8.2 and above.
- Sodium Chloride Solution (NaCl), at 0.155M, is physiologically suitable for for general cell culture work, such as washing cells or diluting compounds for cell treatment.
- Sodium Hydroxide (NaOH), which neutralizes acids, can be used as a general titration base for cell culture applications.
Chondrocytes cultured in monolayer quickly lose their phenotypic characteristics and no longer express Collagen type II and sulfated proteoglycan. Encapsulation of de-differentiated chondrocytes for 3 to 4 weeks in alginate beads will induce re-differentiation and ECM production in chondrocytes.
- Calcium Chloride Solution is formulated to induce polymerization of Sodium Alginate.
- Chondrogenesis Kit contains all media & solutions for the encapsulization of chondrocytes in alginate beads
- Sodium Alginate encapsulates chondrocytes to maintain their phenotypic characterization after isolation or to induce cultured chondrocytes to re-differentiate to chondrocytes.
- Depolymerization Solution (DS) consists of sodium citrate, and dissolves alginate beads to release re-differentiated chondrocytes.
Instructions for Releasing Re-differentiated Chondrocytes from Alginate Beads
- Remove Chondrocyte Differentiation Medium
- Wash the beads 2 times with 0.155 M NaCl
- Add 3 volume of Depolymerizatiojn Solution per volume of packed alginate beads
- Mix at room temperature for 30 minutes
- Apply gentle agitation until the beads have completely dissolved
- Pellet re-differentiated chondrocytes at 1000 rpm for 10 minutes
- Wash the cells 2 times with 0.155 M NaCl
