Medium BGJ was originally developed by Biggers, Gwatkin and Judah in the early 1960's at the Wistar Institute. Subsequent studies resulted in a modification designated BGJb which has been used for supporting cultures of cartilaginous embryonic bone. An additional modification, developed by Sylvia Fitton-Jackson at Strangeways Laboratory in England, is further enriched over the prior formulae. Additional amino acids and vitamins, and increased buffering capacity conferred by the phosphates in the Fitton-Jackson modification, create conditions that permit calcification and growth of cartilaginous embryonic bone.


Directions per Liter: Dissolve 13.47g in 800-900ml of ddH2O stirring gently until completely solubilized. Add 3.5g sodium bicarbonate while stirring. Adjust pH of the medium to 0.1-0.3 pH unit below the desired level. Add additional water to bring the solution to1L Filter-sterilize using a 0.22 micron membrane filter. Aliquot into sterile containers. Do not autoclave. Contains heat-labile compounds that can be damaged with autoclaving.

Storage and Stability: Store powdered media at RT. Opened bottles should be capped tightly and kept in a dark, low humidity environment. Prepared media should be kept at 4°C and used within a short period of time.

Appearance: White to tan, homogenous, free flowing powder.

Solubility (13.5g/L): Clear, yellow, complete

pH: 5.6 ± 0.4

Endotoxin: ~10EU/mg
