CAS 898531-99-2

Pbs 57

Description:

The chemical substance referred to as "Pbs 57" with the CAS number 898531-99-2 is a type of lead sulfide, specifically a nanomaterial that exhibits unique properties due to its nanoscale dimensions. Lead sulfide (PbS) is a semiconductor with a narrow bandgap, making it useful in various applications, including infrared detectors and photovoltaic cells. The "57" in its name may indicate a specific formulation or modification of the material, potentially relating to its size, surface characteristics, or functionalization. As a nanomaterial, it may display enhanced reactivity and altered physical properties compared to bulk lead sulfide, such as increased surface area and quantum confinement effects. However, it is important to note that lead compounds can be toxic, and appropriate safety measures should be taken when handling them. The specific characteristics, such as solubility, stability, and reactivity, can vary based on its synthesis method and intended application. Always refer to safety data sheets and relevant literature for detailed information on handling and usage.

PBS 57

Controlled Product

CAS: 898531-99-2

Applications A galactosylceramide derivative used in the treatment of influenza. PBS-57 has the ability to stimulate both a cell-mediated and humoral immune response. Co-administration of PBS-57 with a vaccine may be used in methods to stimulate one or more of a humoral immune response, a CD4+ T cell response, and a CD8+ cytotoxic T cell response.

PBS 57

CAS: 898531-99-2

PBS 57 is a pluripotent cell-derived protein that has been shown to be a potent vaccine adjuvant. PBS 57 is derived from the plasma of pregnant women and contains the following antigenic determinants: glucose, human albumin, and human immunoglobulin G. PBS 57 can stimulate both humoral and cellular immunity in mice with deficiencies in antibody production or T cells. PBS 57 has also been shown to have strong pro-inflammatory cytokine activity, which may be due to its ability to induce galacturonic acid release from macrophages.
