In the 1920s, composition of salt solutions was formulated specifically for cell cultures, for example, Pannett and Compton (1924), Gay (1936), Earle (1943) or Hanks salts (1948). Establishing formulas of salt solutions was the first step to define cell cultures requirements. The scientists ...

Other known locations of somatic stem cells are teeth, blood vessels, ovarian epithelium and testis. When isolated from the body, somatic stem cells have shown a limited capacity to divide, making in vitro studies difficult to conduct. In order to demonstrate that a population of cells has ...
He systematically investigated the autofluorescence of bacteria, protozoa, and various animal organs such as teeth. Also, he surveyed many organic substances of biological origin, such as albumin, chitin, elastin, gelatin, glycogen, hemoglobin, keratin, and melanin. He confirmed that hemoglobin and ...
Briefly, 20 mL of 5 mg/mL MTT solution (Sigma Aldrich, 5 mg/mL) was added to each well and incubated for 4 h. The medium was discarded, formazan salts were dissolved with vibration in 150 mL dimethylsulfoxide (DMSO) (Sigma Aldrich), and the dishes were read at 490 nm...
a. Degas stacking gel solution completely prior to casting; increase ammonium persulfate and TEMED concentrations by 25%, for stacking gel or low %T, leave APS the same and double the TEMED concentration. b. Remove the salts by dialysis, desalting column, Micro Bio-Spin™ columns, etc. c...

Composition: Mostly water but some proteins, enzymes, nucleic acids (DNA and RNA), carbohydrates, lipids, sugars, and salts Function: Site for the cell's biochemical and synthetic activities Chromosome (Nucleoid) Composition: Long double helix of DNA wrapped around protein molecules formed into a ...
Calcium plays an essential physiological role in the body. Its salts are the minerals that constitute bone. In addition, Ca2+dissolved in the body fluids is essential to many biochemical processes, including nerve excitability, muscle contraction, hormone secretion, regulation of enzymes, and blood ...
Pien Tze Huang (PZH) is a well-known Traditional Chinese Medicine (TCM), characterized by a multitude of pharmacological effects, such as hepatoprotection and inhibition of inflammation and cell proliferative conditions. Many of these effects have been v
