Biolegend, 123531, Ultra-LEAF™ Purified anti-mouse CD1d (CD1.1, Ly-38) Antibody, 100μg

CD1d, also known as CD1.1 and Ly-38, is a 48 kD type I membrane glycoprotein that is structurally similar to MHC class I and is non-covalently associated with β2-microglobulin. In humans, the CD1 family consists of group I (CD1a, CD1b, and CD1c), group II (CD1d), and group III (CD1e) proteins, but CD1d is the only CD1 molecule found in mice. Mouse CD1d has broad tissue distribution, and is found on leukocytes, dendritic cells, epithelial cells, and thymocytes. CD1d plays a role in presenting non-peptide glycolipid antigens to CD1d-restricted T cells, and PKCδ has been identified as a critical regulator of CD1d-mediated antigen presentation.

Q: Do you guarantee that your antibodies are totally pathogen free?
A: BioLegend does not test for pathogens in-house aside from the GoInVivo™ product line. However, upon request, this can be tested on a custom basis with an outside, independent laboratory.
Q: Does BioLegend test each Ultra-LEAF™ antibody by functional assay?
A: No, BioLegend does not test Ultra-LEAF™ antibodies by functional assays unless otherwise indicated. Due to the possible complexities and variations of uses of biofunctional antibodies in different assays and because of the large product portfolio, BioLegend does not currently perform functional assays as a routine QC for the antibodies. However, we do provide references in which the antibodies were used for functional assays and we do perform QC to verify the specificity and quality of the antibody based on our strict specification criteria.
Q: Does BioLegend test each Ultra-LEAF™ antibody for potential pathogens?
A: No, BioLegend does not test for pathogens in-house unless otherwise indicated.  However, we can recommend an outside vendor to perform this testing as needed.
Q: Have you tested this Ultra-LEAF™ antibody for in vivo or in vitro applications?
A: We don't test our antibodies for in vivo or in vitro applications unless otherwise indicated. Depending on the product, the TDS may describe literature supporting usage of a particular product for bioassay. It may be best to further consult the literature to find clone specific information.
