Defined Keratinocyte-SFM is a serum-free medium optimized for the isolation and expansion of human keratinocytes without the need for bovine pituitary extract (BPE) supplementation or the use of fibroblast feeder layers (1,2). The growth-promoting activity of BPE has been replaced by the inclusion of growth promoting agents which enhance consistent product performance. These growth-promoting agents also maintain cell morphology, physiological markers, and growth. The medium is formulated to inhibit fibroblast proliferation and has a low calcium concentration ( Note: This formulation contains s...

Collagenase is a protease with specificity for the bond between a neutral amino acid (X) and glycine in the sequence Pro-X-Glyc-Pro. This sequence is found in high frequency in collagen. Collagenase is unique among proteases in its ability to degrade the triple-helical native collagen fibrils commonly found in connective tissues such as skin, tendon, blood vessels, and bone. Collagenase disaggregation has been suitable for the culture of human tumors, mouse kidney, human adult and fetal brain, and many other tissues including epithelium. It is relatively gentle, dissociates well at physiologic...

Dispase II (neutral protease) is an amino-endo peptidase that hydrolyses N-terminal peptide bonds of non-polar amino acid residues. This sequence is found in high frequency in collagen. Dispase II has a mild proteolytic action that makes it useful for the isolation and routine passaging of primary cells. It is relatively gentle, dissociates well at physiological temperature and pH, and generally maintains cell membrane integrity. Gibco® Dispase II is produced in Bacillus polymyxa and packaged as a lyophilized, non-sterile powder for research use in cell or tissue dissociation and to prevent cl...

SuperScript® II Reverse Transcriptase (RT) is an improved version of SuperScript® RT. It is a DNA polymerase that synthesizes a complementary DNA strand from single-stranded RNA, DNA, or an RNA:DNA hybrid. This enzyme is genetically engineered by the introduction of point mutations in the RNase H active center to reduce RNase H activity. This structural modification eliminates degradation of RNA molecules during first-strand cDNA synthesis and gives SuperScript® II RT superior performance characteristics. • Yield – Reduced RNase H activity results in greater first-strand cDNA yields • Size of ...

The XCell line of mini-cells has always distinguished itself by being simple, sturdy, and convenient. The tradition continues with the patented XCell SureLock ® Mini-Cell. The incorporation of a gel tension wedge in place of the rear wedge used on earlier models makes the XCell SureLock ® the easiest-to-use mini-cell on the market. How the System Works The XCell SureLock ® Mini-Cell holds gels firmly with a simple gel tension wedge. When the lever on the gel tension wedge is pushed forward into the locked position, an even horizontal force is generated. This seals the gel/buffer core assembly ...

The PKC family of serine⁄threonine kinases, including PRKCB2 (PKC beta II), is activated intracellularly by signal transduction pathways. In humans, at least 12 different PKC polypeptides have been identified. These isoforms differ in primary structure, tissue distribution, subcellular localization, mode of action in vitro, response to extracellular signals, and substrate specificity. PKC alpha, beta I, beta II and gamma form the conventional family; their activities are Ca2+- and phospholipid-dependent.
