Background of CD1D

CD1D (CD1d molecule) also known as R3G1, Antigen-presenting glycoprotein CD1d, R3G1, CD1D, is the sole group-2 member of the CD1 family of major histocompatibility (MHC)-like glycoproteins. Expressed on the surface of various human antigen-presenting cells. They are related to the class I MHC molecules, and are involved in the presentation of lipid antigens to T cells. It is the only member of the group 2 CD1 molecules. CD1d presented lipid antigens activate a special class of T cells, known as Natural Killer T (NKT) cells. When activated, NKT cells rapidly produce Th1 and Th2 cytokines, typically represented by interferon-gamma and IL-4 production. Jayawardena-Wolf et al. described 2 different pathways of Cd1d trafficking to endosomal compartments in mouse cells. A tyrosine-based motif governs recycling between the plasma membrane and the endosome, while Cd1d associates, like major histocompatibility complex class II antigens, with the invariant chain, or II, in the endoplasmic reticulum. Both pathways enhance antigen presentation to Cd1d-restricted natural killer T cells.

6 Customer Q&As for Anti-CD1d Antibody


Would anti-CD1d antibody PA1850 work on feline IHC with pancreas?

Verified Customer

Verified customer

Asked: 2020-03-10


Our lab technicians have not tested anti-CD1d antibody PA1850 on feline. You can run a BLAST between feline and the immunogen sequence of anti-CD1d antibody PA1850 to see if they may cross-react. If the sequence homology is close, then you can perform a pilot test. Keep in mind that since we have not validated feline samples, this use of the antibody is not covered by our guarantee. However we have an innovator award program that if you test this antibody and show it works in feline pancreas in IHC, you can get your next antibody for free.

Does PA1850 anti-CD1d antibody work on parafin embedded sections? If so, which fixation method do you recommend we use (PFA, paraformaldehyde, other)?

E. Carter

Verified customer

Asked: 2019-09-10


As indicated on the product datasheet, PA1850 anti-CD1d antibody as been tested on IHC. It is best to use PFA for fixation because it has better tissue penetration ability. PFA needs to be prepared fresh before use. Long term stored PFA turns into formalin, as the PFA molecules congregate and become formalin.

I was wanting to use your anti-CD1d antibody for IHC for human leukemic t-cell on frozen tissues, but I want to know if it has been tested for this particular application. Has this antibody been tested and is this antibody a good choice for human leukemic t-cell identification?

Verified Customer

Verified customer

Asked: 2019-04-19


You can see on the product datasheet, PA1850 anti-CD1d antibody has been validated for IHC, WB on human tissues. We have an innovator award program that if you test this antibody and show it works in human leukemic t-cell in IHC-frozen, you can get your next antibody for free.

We are currently using anti-CD1d antibody PA1850 for human tissue, and we are satisfied with the WB results. The species of reactivity given in the datasheet says human. Is it likely that the antibody can work on dog tissues as well?

Verified Customer

Verified customer

Asked: 2017-06-28


The anti-CD1d antibody (PA1850) has not been tested for cross reactivity specifically with dog tissues, though there is a good chance of cross reactivity. We have an innovator award program that if you test this antibody and show it works in dog you can get your next antibody for free. Please contact me if I can help you with anything.

Is this PA1850 anti-CD1d antibody reactive to the isotypes of CD1D?

O. Edwards

Verified customer

Asked: 2013-07-12


The immunogen of PA1850 anti-CD1d antibody is A synthetic peptide corresponding to a sequence at the N-terminus of human CD1d(76-92aa FSDQQWETLQHIFRVYR). Could you tell me which isotype you are interested in so I can help see if the immunogen is part of this isotype?
