Highly active MEGACD40L® oligomer mimics in vivo membrane-assisted CD40L aggregation and stimulation without the need for enhancers
High purity with low endotoxin levels
Experienced manufacturing results in consistent and dependable lot-to-lot performance
Optimized formulation for improved stability and enhanced activity
MEGACD40L® is a high activity protein in which two trimeric CD40 ligand molecules are artificially linked via the collagen domain of Adiponectin/ACRP30/AdipoQ. This protein very effectively simulates the natural membrane-assisted aggregation of CD40L in vivo. It provides a simple and equally potent alternative to [CD40L+enhancer] combinations (Prod. No. ALX-850-064).
Product Details
| Alternative Name: | CD40L:ACRP30headless, CD154:ACRP30headless, TNFSF 5:ACRP30headless, gp39:ACRP30headless |
|
| MW: | ~38kDa |
|
| Source: | Produced in CHO cells. The extracellular domain of human CD40L (CD154) (aa 116-261) is fused at the N-terminus to mouse ACRP30headless (aa 18-111) and a FLAG®-tag. |
|
| UniProt ID: | P29965 (human CD40L), Q60994 (mouse Adiponectin) |
|
| Concentration: | 0.1mg/ml after reconstitution. |
|
| Formulation: | Lyophilized. Contains PBS. |
|
| Purity: | ≥90% (SDS-PAGE) |

B cell lymphocyte activation by MEGACD40L® (Prod. No. ALX-522-110). Method: Peripheral Blood Mononuclear Cells (PBMCs) were incubated at 37°C, 5% CO2 for 48 hours in 48 well plates (1 x 106 cells/well). Each well contained 200µl serum free test media with serially diluted MEGACD40L®. After treatment, cells were washed and dual-stained with mouse anti-human CD19–PE and mouse anti-human CD86–APC and analyzed by flow cytometry. The data are presented as the percent of CD19 positive B cells that co-stain as CD86 positive, at each concentration of MEGACD40L®.
