POU2AF1 Antibody / BOB-1

• Catalog Number: orb606630
• Category: Antibodies
• Description: BOB1, also called POU2AF1, expression in a variety of established B-cell lines, representing different stages of B-cell development, has suggested a constitutive, B-cell-specific expression pattern. LP cells in nodular lymphocyte predominant Hodgkin lymphoma, because they are germinal center-derived, are consistently immuno-positive for BOB1. Conversely, only some cases of classical Hodgkin lymphoma show BOB1 immuno-reactivity within the Hodgkin and Reed-Sternberg cells. Expression of BOB1 has been reported in follicular center cell lymphoma, diffuse large B-cell lymphoma and some cases of acute myeloid leukemia. B-CLL, marginal zone lymphoma, and mantle cell lymphoma may show weak to moderate immunoreactivity.

Analysis of HuProt (TM) microarray containing more than 19, 000 full-length human proteins using BOB1 antibody (clone BOB1/2425). These results demonstrate the foremost specificity of the BOB1/2425 mAb. Z- and S- score: The Z-score represents the strength of a signal that an antibody (in combination with a fluorescently-tagged anti-IgG secondary Ab) produces when binding to a particular protein on the HuProt (TM) array. Z-scores are described in units of standard deviations (SD's) above the mean value of all signals generated on that array. If the targets on the HuProt (TM) are arranged in descending order of the Z-score, the S-score is the difference (also in units of SD's) between the Z-scores. The S-score therefore represents the relative target specificity of an Ab to its intended target.
