Gibco® HEPES (N-2-Hydroxyethylpiperazine-N-2-Ethane Sulfonic Acid) is a zwitterionic organic chemical buffering agent commonly used in cell culture media. The addition of 10 – 25 mM HEPES provides extra buffering capacity when cell culture requires extended periods of manipulation outside of a CO 2 incubator. HEPES is a good buffering choice for many cell culture systems because it is membrane impermeable, has limited effect on biochemical reactions, is chemically and enzymatically stable, and has very low visible and UV light absorbance. Product Use For in vitro diagnostic use. Dual-site cGMP...

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...

SKP2 (S-phase Kinase-associated Protein 2) belongs to the family of F-box proteins that interact with the Cyclin A-Cdk2 complex. In tumor tissues, SKP2 is expressed widely, such as colon mucinous carcinoma, gastric adenocarcinoma, breast cancer, melanoma, prostate adenocarcinoma, with particularly higher expression on lung adenocarcinoma, lung squamous carcinoma, squamous carcinoma of cervix, endometrial carcinoma, ovary serous carcinoma and leiomyosarcoma. A recent study suggests that SKP2 plays a role in oncogenesis and is involved in the pathogenesis of lymphomas. Positive tissue: Breast ca...
