Furthermore, cell surface reactivity to HS could be detected by the 10E4 antibody in the syndecan-1/EGFP transfected cells.
The main outcome measures were i) endothelial cell reactivity to Abs assessed qualitatively and semi-quantitatively (see below); ii) ELISA quantification of conditioned media reactivity; iii) flow cytometric quantification of cell surface reactivity; and iv) comparison of transcript detectability by single and nested rt-PCR reactions.
To address this, our immunization was performed with fusion protein MAR3-MBP (MAR3; amino acids 984-1224 of MRP3), which may contain extracellular epitopes of MRP3, and serum titer was monitored by the reactivity with MRP3-expressing GBM cells under conditions detecting cell surface reactivity only.
Expression of SMIM1 cDNA in Vel− cultured cells generated anti-Vel cell surface reactivity, confirming that SMIM1 encoded the Vel blood group antigen.
Regulation of Kv2.1 K conductance by cell surface channel density.
The results showed that both 27.B1 and 27.F7 antibodies demonstrate positive cell-surface reactivity against the breast cancer cell line, SKBR-3.
By indirect cell surface radioimmunoassay, a cultured cell line panel consisting of 17 gliomas, 3 medulloblastomas, 2 neuroblastomas, 2 melanomas, and 2 fetal and 2 adult brain-derived cell lines was examined; the two Mabs were highly similar but distinct in their reactivity profiles.
Surface modifications affect the toxicity by modifying the surface reactivity and the ability to aggregate with bacteria [108, 110].
Flow cytometric analysis of WT, neo and each of the four gsv transfectants demonstrated measurable levels of antibody reactivity (cell surface expression in intact cells) for ICAM-2 protein only for cells expressing WT and gsv4,5, even though gsv1,4,5, gsv1,2,5, and gsv1-6 were clearly seen by immunoblot.
These findings indicate that Trx1 reactivity of cell surface receptors is selective and is not determined by the presence of CRDs or the number of ectodomain disulfide bonds.
