From Google Video Search: "cytotoxicity" Can someone tell me what this means? I have spent hours trying to figure it out.? Q. Trimethylchitosan, or quaternised chitosan, has been shown to transfect breast cancer cells; with increased degree of trimethylation increasing the cytotoxicity and at approximately 50% trimethylation the derivative is the most efficient at gene delivery. My guess is that it mutates the cancer cells or does it replicate them and increase there vitality. Asked by ricodiva - Tue May 25 22:10:06 2010 - - 1 Answers - 1 Comments A. Sometimes Wikipedia writes the darnest things. Chitosan in this case is used as a transfection factor, ie to make cell membranes open up or (have pores) to allow genes to enter these cells. But the risk of increasing the amount of chitosan used also damages (or kills) the cells due to increased cytotoxicity. approximately 50% trimethylation the derivative is the most efficient at gene delivery Answered by stormalive_32722 - Wed May 26 00:12:33 2010 does the cytotoxicity test always requires the use of shrimp(brine)?

Extracellular HSP70 on the other hand can activate cells of the innate and adaptive immune system. Acute overexpression of intracellular HSP70 could even increase the susceptibility of melanoma cells to cytotoxic T-lymphocytes (CTLs) that use the granule-exocyto sis pathway for killing (Dressel et al. 1999). To decipher the molecular pathway of this increased susceptibility to CTLs, the effect of the acute overexpression of HSP70 on gene expression was analysed in cells, in which Hsp70 is under the control of a tetracycline-in ducible promoter. To reduce the complexity of CTL-induced apoptosis, further experiments were performed with granzyme (Gr)B, a component of the cytotoxic granules of CTLs and NK cells, that has been shown to interact with HSP70. Heparan sulphates on the other hand are involved in Gr B-binding to target cells of CTLs and are modified in their sulphation pattern by sulphatases 1 and 2. The role of HSP70 and sulphatases 1 and 2 in Gr B-induced apoptosis is analysed.  @ antibodies-online Store: antibodies-online Price: $414.60 USD Condition: new anti-Cytotoxic T-lymphocyte-as sociated Protein 4 (CTLA4), Extracellular Domain antibody reacts with: Human.
