Description:
The Ber-H2 monoclonal antibody specifically reacts with human CD30, a 120kDA type I transmembrane glycoprotein of the tumor necrosis factor receptor superfamily (TNFR) also known as the Ki-1 antigen. CD30 can elicit signals leading to either activation or apoptosis through interaction with CD30 ligand (CD30L). It is expressed by a subset of extrafollicular activated B and T cells, lung macrophages, activated NK cells, lymphomas, and endothelial cells. It is highly expressed on Hodgkins and Reed-Sternberg cells.
Description:
Produced through a multi-stage process that includes delipidation, salt fractionation, ion-exchange chromatography, gel filtration, and affinity chromatography. No contaminating proteins are observed when assayed at a protein concentration of 20mg/mL against anti-whole serum or anti-fragment specific antisera. All immunoglobulin fragments are prepared from highly purified, whole molecules subject to enzymatic digestion.
Description:
The J116 monoclonal antibody specifically reacts with human Programmed death-1 (PD-1 or CD279), a 50-55 kDA glycoprotein. It is expressed on mainly on activated B, T, and myeloid cells. Within the cytoplasmic region, PD-1 contains an Immunoreceptor tyrosine-based inhibitory motif (ITIM) and seems to regulate peripheral tolerance. The lack or mutation of CD279 is linked to autoimmune disorders.The J116 antibody does not block the binding of the PD-1 ligand, but does inhibit the PD-1 signal transduction.

Description:
The 17A2 monoclonal antibody specifically reacts with the mouse T lymphocytes receptor (TCR) associated CD3 complex, resulting in cellular activation and proliferation. CD3 is expressed by thymocytes and mature lymphocytes, and contains γ, δ, and ε subunits, involved in the assembly, trafficking, and surface expression of T-cell receptor complex. The interaction between the T lymphocytes and the 17A2 antibody can be blocked by the 145-2C11 anti-CD3e antibody, demonstrating that the 17A2 antibody recognizes the CD3 ε chain.

Description:
The polyclonal antibody to Csn6 was generated by immunisation of rabbits with a synthetic peptide corresponding to residues [283-297] of the human Csn6 sequence. The antibody has been characterised by one-dimensional Western blotting. Vial contains a partially purified immunoglobulin preparation suspended phosphate-buffered saline containing 0.01M sodium azide. The COP9 signalosome, once defined as a repressor complex of light activated development in Arabidopsis, has recently been found in humans and is probably present in most multicellular organisms. The COP9 signalosome is closely related to the lid sub-complex of the 26S proteasome in structural composition and probably shares a common evolutionary ancestor. A multifaceted role of the COP9 signalosome in cell-signalling processes is hinted at by its associated novel kinase activity, as well as the involvement of its subunits in regulating multiple cell-signalling pathways and cell-cycle progression. The molecular genetic studies in Arabidopsis suggest that the complex functions as part of a highly conserved regulatory network, whose physiological rüle in animals has yet to be determined. The COP9 signalosome, also known as the the COP9 complex and JAB1-containing signalosome, is a conserved nuclear protein complex found in plants and animals. It is composed of eight distinct subunits, designated S1 to S8 (very recently re-designated Csn1-Csn8) according to the molecular weight of the mammalian complex subunits. Subunit composition and the subunit sequences are substantially conserved between the mammalian and the plant complexes, implying that the complex has a conserved cellular function in higher eukaryotic organisms. The role and function of Csn6 has yet to be determined although this subunit is known to interact with subunits Csn2 and Csn7 within the COP9 signalosome.
Description:
The HIB19 monoclonal antibody reacts with a human 95 kDa transmembrane glycoprotein known as CD19, which is expressed by B lymphocytes during all the developmental stages, except for the terminally differentiated plasma cells. CD19 is also expressed on follicular dendritic cells, and seems to ensure the regulation of B lymphocytes proliferation. CD19, CD21, CD81, MHC class II, and Leu13 can bind together and form a complex which associates with the B cell receptor (BCR) on the surface of B lymphocytes and facilitates the signal transduction.
