This product was changed from ascites to tissue culture supernatant on 25th October 2016. The following lot(s) is/are from ascites and is still in stock as of 25th October 2016 - GR288674, GR272407. Lot numbers higher than GR288674, GR272407 will be from tissue culture supernatant. Please note that the dilutions may need to be adjusted accordingly

Storage in frost-free freezers is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use.

Many cellular activities depend on the interaction of cells with the surrounding extracellular matrix (ECM). Most cells, in intact tissue and in culture, are attached to an ECM. Epithelial cells are associated with the basement membrane; fibroblastic cells are usually embedded in a pericellular mesh of fibrils, and tissue culture cells usually grow on a substrate which is covered by various ECM components. Studies have indicated that the matrix or its various isolated components provide not only adhesive surfaces for cells to grow on but also have effects on the rate of cell growth, mobility, morphogenesis and differentiation. Within the ECM several glycoproteins and proteoglycans have been identified. It has been proposed that the different constituents interact with each other in a rather complex fashion. The poor antigenicity of proteoglycans especially their glycoaminoglycan (GAG) moieties make it difficult to localize these molecules in tissue and cell culture. Monoclonal Anti-Chondroitin Sulfate can be used to study chondroitin sulfate proteoglycan (CSPG) distribution and its relationships to specific cell-substrate contacts.

The Life Science industry has been in the grips of a reproducibility crisis for a number of years. Abcam is leading the way in addressing the problem with our range of recombinant monoclonal antibodies and knockout edited cell lines for gold-standard validation.

One factor contributing to the crisis is the use of antibodies that are not suitable. This can lead to misleading results and the use of incorrect data informing project assumptions and direction. To help address this challenge, we have introduced an application and species grid on our primary antibody datasheets to make it easy to simplify identification of the right antibody for your needs.
