Informazioni sul gene

human ... CD40LG(959)

Applicazioni

Coating a plate well (6 well plate) with this recombinant CD40 protein in neuronal cell specific medium at 1-10 μg/well (6 well plate) allows for 1) human neuronal cell / receptor interaction studies or 2) use as a culture matrix protein for human neuronal axon connection studies in vitro.

Use this procedure as a guideline to determine optimal coating conditions for the culture system of choice.
1.Thaw CD40 and dilute to desired concentration using serum-free medium or PBS. The final solution should be sufficiently dilute so the volume added covers the surface evenly (1-10 μg/well, 6 well plate).
2.Add appropriate amount of diluted material to culture surface.
3.Incubate at room temperature for approximately 1.5 hours.
4.Aspirate remaining material.
5.Rinse plates carefully with water and avoid scratching bottom surface of plates.
6.Plates are ready for use. They may also be stored at 2-8 °C damp or air dried if sterility is maintained.

Nota sulla preparazione

The full-length extracellular domain of the human CD40 gene (54-608 aa) was constructed with 29 N-terminal T7/HIS-tag and expressed in E. coli as inclusion bodies. The final product was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified.

Successful gene therapy will require targeted delivery vectors capable of self-directed localization. In this regard, the use of antibodies or single chain antibody fragments (scFv) in conjunction with adenovirus (Ad) vectors remains an attractive means to achieve cell-specific targeting. However

B lymphocytes with regulatory or effector functions synthesize granzyme B (GZMB). We investigated the frequency and phenotype of GZMB-producing B cells in breast tumor-draining lymph nodes (TDLNs). Mononuclear cells were isolated from 48 axillary lymph nodes and were stimulated with

Humoral immunity requires B cells to respond to multiple stimuli, including antigen, membrane and soluble ligands, and microbial products. Ets family transcription factors regulate many aspects of haematopoiesis, although their functions in humoral immunity are difficult to decipher as a

Two human B-cell differentiation antigens, Bp35 and Bp50, apparently play distinct roles as signal receptors in B-cell activation. Monoclonal antibodies (mAbs) to either Bp35 or Bp50 deliver positive signals to B cells that stimulate their transition through the cell cycle.

The in vivo therapeutic efficacy of DC-based cancer vaccines is limited by suboptimal DC maturation protocols. Although delivery of TLR adjuvants systemically boosts DC-based cancer vaccine efficacy, it could also increase toxicity. Here, we have engineered a drug-inducible, composite activation
