Description: This L161 monoclonal antibody detects CD1c (also known as BDCA-1), a glycoprotein that is noncovalently linked to beta-2 microglobulin on thymocytes and antigen presenting cells such as dendritic and Langerhans cells. This molecule is also expressed on some circulating and marginal zone B cells, as well as in lymph nodes and germinal centers. CD1c is involved in the presentation of lipid antigens such as microbial fatty acids to effector T cells during the adaptive immune response. Finally, alternative splicing gives rise to three different isoforms of CD1c (soluble, membrane, and cytoplasmic/soluble isoforms).

Applications Reported: This L161 antibody has been reported for use in flow cytometric analysis.

Applications Tested: This L161 antibody has been pre-diluted and tested by flow cytometric analysis of normal human peripheral blood cells. This may be used at 5 µL (0.25 µg) per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test.

Super Bright 600 is a tandem dye that can be excited with the violet laser line (405 nm) and emits at 600 nm. We recommend using a 610/20 bandpass filter. Please make sure that your instrument is capable of detecting this fluorochrome.

When using two or more Super Bright dye-conjugated antibodies in a staining panel, it is recommended to use Super Bright Complete Staining Buffer (Product # SB-4401) to minimize any non-specific polymer interactions. Please refer to the datasheet for Super Bright Staining Buffer for more information.

Light sensitivity: This tandem dye is sensitive to photo-induced oxidation. Please protect this vial and stained samples from light.

Fixation: Samples can be stored in IC Fixation Buffer (Product # 00-8222) (100 µL of cell sample + 100 µL of IC Fixation Buffer) or 1-step Fix/Lyse Solution (Product # 00-5333) for up to 3 days in the dark at 4°C with minimal impact on brightness and FRET efficiency/compensation. Some generalizations regarding fluorophore performance after fixation can be made, but clone specific performance should be determined empirically.

Excitation: 405 nm; Emission: 600 nm; Laser: Violet Laser
