RDI Divison of Fitzgerald Industries Intl  offers a wide line of  antibodies. Since no one antibody works best for all applications (flow cytometry, neutralization, blotting, histochemistry, ELISA, etc), we offer many different types of antibodies to help solve this problem. Please inquire for other applications or types of antibodies not listed below. All products are for in vitro research use only-not for use in or on humans or animals-not for use in diagnostics.

PRESENTATION: Each monoclonal is delivered in a sealed vial at a concentration of 200ug in 2ml phosphate buffered saline solution with 1mg/ml BSA and 10mM NaN3 .We recommend that each laboratory determine an optimum working titre for use in its particular application.

STORAGE: Purified monoclonal antibodies are generally stable for long periods at 4oC. However repeated warming to room temperature and re-cooling may result in a loss of activity and hence effective working titre. It is recommended that monoclonal antibodies are aliquotted upon receipt and then stored at -200C. After thawing they should then be used as a stock solution for up to 60 days. Dilute working solutions are best prepared on the day of use.

Immunogen: A 20 residue peptide corresponding to amino acids 258-277 of the human CD40 sequence (CQPVTQEDGKESRISVQERQ) coupled to KLH.

Use: Working dilution: 1:250 for immunoblotting (colorimetric) > with chemiluminescence. Titer for each application.

Specificity: Recognizes a 43 kDa band corresponding to the expected molecular weight of CD40 by SDS-PAGE. Reacts with CD40 in human, mouse, rat, pig, and monkey cells.

Storage: -20°C. Recommend aliquot and store at -20 DEG C. Avoid frequent freeze thaw cycles. At first thaw, tighten cap and centrifuge for 1 minute 1000rpm to concnetrate material in vial.

LOT# see sheet with shipment

CLONE: 24-31

Activity: Reacts with human CD40L. This antibody immunoprecipitates a CD40L (gp39) molecule of 36 kd. The antibody will stain activated CD3+human PBL and will functionally block MLR, sgp30 induced B cell proliferation and T cell dependent B cell differentiation.

Application: -Indirect fluorescence (approx 0.8ug/500K cells) -Briefly, ficoll prepared human peripheral white blood cells were stimulated by incubating 6 hours at 5 million cells/ml in RPMI 10% FBS media including 3ug/ml phytohemagglutinin-P and 1ng/ml Phorbol 12- Myristate 13-acetate. 500K cells were then washed and incubated 45 minutes on ice with 80ul of product at 10ug/ml. Cells were washed 2X and incubated with 50ul of secondary antibody and then washed 3X. A net of 5% of population of the cells stained positive with a mean shift of 306 fluorescent units compared to the IgG1 negative control.

-Blocking experiments-MLR (mixed Lymphocyte Response) can be blocked using approx 10ug/ml when 300K human PBL's(responders) are cultured with 100K irradiated allogenic human PBL's (stimulators). Inhibition can be observed by day 5 when using a 3H thymidine pulse to monitor proliferation. B cell differentiation induced by activated T cells and Il-2 can be measured by Ig production of IgD+ naive B cells.

Monoclonal anti-CD40L significantly inhibits this Ig   production at levels of 1-10ug/ml.

-titers must be determined for each application

Storage: Store at 4 Deg C. DO NOT FREEZE.
Precautions: For In vitro research Use Only. Not for use in or on humans or animals or for diagnostics.

DATA SHEET: mouse anti-human CD40L (CD154) clne TRAP1

Catalog#: RDI-CD154abm-TP   $406.00/100ug

Package Size: 100ug purified in 50mM Tris-HCL (pH 8.0) with 0.01% NaN3.

       also available azide free: cat#RDI-CD154abm-TPX  $1000.00/0.5mg

Species: mouse IgG1k

Clone: TRAP-1

Workshop: VI, id#6T-068

Purification: By Protein G from supernatant.

Activity: Reacts with CD40-Ligand (newly clustered as CD154 in VIth workshop), a 39 kd type II membrane glycoprotein expressed on activated T cells. CD40-CD40L interaction plays a very important role in T cell depenednet B cell proliferation, differenetiation, and memory cell formation. CD40L MAB partially blocks T cell-B cell interaction affecting subsequent proliferation, IL-2R expression and differentiation on B cells. In addition, blocking of CD40-CD40L, interaction has been demonstrated with soluble CD40, resulting in the inhibition of immunoglobulin isotype switching. It has been reported that patients with X linked hyper-IgM syndrome have defective expression of functional CD40L due to a defective gene that encodes CD40L.
