A novel testing method determines the amount of organic compounds sorbed to sediments. It is a nonextractive immunoassay which has demonstration data for 2,4-dinitrobenzene sulfonate (a model pollutant for which antibodies are commercially available)

Recently we reported that the expression of the enzyme alkaline phosphatase (APase) is a marker for B cell activation. Enzymatic activity was found only in activated B cells and not T cells. Using flow cytometry we showed that some of the APase was f

Two long-term cultured cell lines were established from BALB/c mouse axillary and cervical lymph nodes that exhibited a combination of functional, morphological, and phenotypic characteristics consistent only with high endothelial venule cells. Splee

Salmonella typhimurium mitogen (STM) is a polyclonal activator of rat B lymphocytes, triggering them to proliferate, but not differentiate, to antibody-secreting cells. When lymphokines in the form of a supernatant from Con A-stimulated splenocytes (

A water-soluble, proteinaceous preparation derived from the cell walls of Salmonella typhimurium Re mutants has recently been tested in our laboratory for its ability to act as a mitogen for rat lymphocytes. We have found this preparation (STM) to be

An in vitro model for the propagation and expansion of the memory B lymphocyte population is described. DNP-BGG immune cells were mixed with OVA immune cells and challenged immediately with DNP-OVA. After the 1st response had begun to wane, the cells

Purified human C3 was found to inhibit rat in vitro secondary antibody responses. Fifty percent inhibition of antibody-forming cell development occurred with C3 concentrations of 26 micrograms/ml. This decrease was not the result of a general toxicit

Lymphocyte proliferation and differentiation result from ordered cellular interactions governed by soluble products (lymphokines). Dissecting the individual steps in these processes has been difficult, due to a paucity of pure lymphokines. Recently,

The ability of insulin to influence the responsiveness of murine T lymphocytes in a culture system containing a serum substitute was documented. The presence of insulin was found to enhance the concanavalin A (Con A) reactivity of the lymphocytes. On
