BD, 572179, BD® OMICS-One B-cell Protein Panel

Reactivity: Human (Tested in Development)
Application: Single Cell 3' Sequencing (Qualified)
Regulatory Status: RUO
Storage Buffer: Lyophilized powder containing BSA and ≤ 0.25% sodium azide.
Description: Description The BD® OMICS-One B-Cell Protein Panel consists of 30 different specificities against major B-cell markers in a single tube. Designed and optimized to work on the BD Rhapsody™ System, the B-Cell Protein Panel is tested to work seamlessly alongside the BD Rhapsody™ Whole Transcriptome Analysis (WTA) Assay, Targeted mRNA Assay, BD® Single-Cell Multiplexing Kit (SMK), BD® Intracellular CITE-seq (IC-AbSeq) Assay, and BD Rhapsody™ TCR/BCR Next Multiomic Assay for humans. The individual antibodies were each conjugated to an oligonucleotide that contains a specific antibody barcode sequence flanked by a polyA tail on the 3' end and a common PCR handle (PCR primer binding site) on the 5' end. All AbSeq barcode sequences were generated in silico with minimal sequence similarity to the human genomes, have low predicted secondary structure, and have high Hamming distance within the BD® antibody-oligo portfolio, to allow for sequencing error correction and unique mapping. The polyA tail of the oligonucleotide allows the barcode sequence to be captured by the BD Rhapsody™ Enhanced Cell Capture Beads. The 5' PCR handle allows for efficient sequencing library generation for various sequencing platforms. Each individual antibody exists at an optimal concentration within the 30-plex to enable superior target and population resolution. The B-Cell Protein Panel is designed with SMART technology. SMART technology helps lower sequencing cost while increasing data resolution by attenuating antibodies that target high-expressing primary markers and by allowing re-allocation of sequencing reads to markers expressed at lower levels. With SMART technology, markers low in expression can be quantified without having to do deeper sequencing and incurring high sequencing cost. The two specificities attenuated in the B-Cell Panel are CD23 and HLA-DR.
Preparation And Storage: Preparation And Storage Store at 2-8°C and protected from prolonged exposure to light. Do not freeze.
Recommended Assay Procedures: Recommended Assay Procedures This reagent is provided lyophilized in a pre-titrated format. 1. Remove the BD® OMICS-One B-Cell Protein Panel tube from the foil bag and bring up to room temperature for 5 minutes. 2. Make sure the pellet is located at the bottom of the tube. If not, briefly centrifuge to collect the contents at the tube bottom. 3. Add 35 µL  of nuclease-free water to the bottom of the tube and allow antibodies to reconstitute for 5 minutes at room temperature. 4. Transfer  the reconstituted antibodies on ice until the cells are ready for staining. Note: Reconstitute antibodies immediately before cell staining. Prolonged incubation of reconstituted antibody might increase the non-specific background. 5. For BD® AbSeq Ab-Oligo drop-in of 60 plex or lower, prepare the BD® AbSeq labeling MasterMix using the procedure in the following two tables in 1.5-mL LoBind tube on ice. Note: For drop-in with more than 60 plex, reach out to technical support for calculation. For sequential labeling with Sample Tags or no Sample Tags, prepare BD® AbSeq labeling MasterMix for drop-ins as follows: ____________________________________________________________________________________________ Component                           1 sample (µL)       1 sample +          2 samples + 30% overage (µL)    30% overage (µL) Per BD® AbSeq Ab-Oligo              2.0                 2.6                 5.2 Total of BD® AbSeq Ab-Oligo         2.0 × N*            2.6 × N             5.2 × N FBS † (catalog number 554656)        140 – (2.0 x N)     182 – (2.6 x N)     364 – (5.2 x N) Total                               140                 182                 364 For co-labeling with Sample Tags, prepare BD® AbSeq labeling MasterMix for drop-ins as follows: ____________________________________________________________________________________________ Component                           1 sample (µL)       1 sample +          2 samples + 30% overage (µL)    30% overage (µL) Per BD® AbSeq Ab-Oligo              2.0                 2.6                 5.2 Total of BD® AbSeq Ab-Oligo         2.0 × N*            2.6 × N             5.2 × N FBS † (catalog number 554656)        120 – (2.0 × N)     156 – (2.6 × N)     312 – (5.2 × N) Total                               120                 156                 312 *  N = number of drop-in antibodies. N = 0 if there are no drop-in antibodies. †  FBS = BD Pharmingen™ Stain Buffer. 6. Pipet-mix the BD® AbSeq labeling MasterMix for drop-ins. Briefly centrifuge to collect the contents at the bottom, and place back on ice. 7. For sequential labeling with Sample Tags or no Sample Tags, for each sample, add 140 µL BD® AbSeq labeling MasterMix of drop-ins to the tube containing 35 µL reconstituted B-Cell Protein Panel solution to make a total volume of 175 µL. For co-labeling with Sample Tags, for each sample, add 120 µL BD® AbSeq labeling MasterMix of drop-ins and 20 µL Sample Tag to the tube containing 35 µL reconstituted B-Cell Protein Panel solution to make a total volume of 175 µL. 8. Pipet-mix the mixture, briefly centrifuge to collect the contents at the tube bottom, and place back on ice. 9. Centrifuge cells at 400 × g for 5 minutes. If Fc Block is used, proceed to step 10. Otherwise, skip to step 11. 10. (Optional) For samples containing myeloid and B lymphocytes, BD Biosciences recommends blocking nonspecific Fc Receptor–mediated false-positive signals with Human BD Fc Block (catalog number 564220). a. To perform blocking, pipet the Fc Block MasterMix into a new 1.5-mL LoBind tube on ice: _________________________________________________________________________________ Component                           1 sample (µL)*    1 sample + 20% overage (µL) FBS† (catalog number 554656)        20.0              24.0 Fc Block‡ (catalog number 564220)   5.0               6.0 Total                               25.0              30.0 *  Sufficient for up to 1 million cells. To block more cells, adjust the volume. †  FBS = BD Pharmingen™ Stain Buffer. ‡ Fc Block =  BD Pharmingen™ Human BD Fc Block. b. Pipet-mix the Fc Block MasterMix and briefly centrifuge. Place on ice. c. Remove the supernatant from the cells without disturbing the pellet. d. Resuspend the cells in 25 µL of Fc Block MasterMix. e. Incubate the cells at room temperature (15 °C to 25 °C) for 10 minutes. f. Add 175 µL of BD® AbSeq labeling MasterMix from Step 8 into the cell suspension. Pipet-mix and proceed to Step 12. 11. Remove the supernatant from the cells without disturbing the pellet. Add 25 µL Stain Buffer (FBS) to the 175 µL of BD® AbSeq labeling MasterMix from Step 8 to make a total volume of 200 µL.Resuspend the cell pellet in 200 µL total volume. Pipet-mix. 12. Transfer the cells with BD® AbSeq labeling MasterMix into a new 5-mL polystyrene Falcon tube. 13. Stain the cells on ice for 30 minutes. 14. Add 3–4 mL Stain Buffer (FBS) to labelled cells and pipet-mix. 15. Centrifuge at 400 × g for 5 minutes. 16. Uncap the tube and invert to decant supernatant into biohazardous waste. Keep the tube inverted and gently blot on a lint-free wiper to remove residual supernatant from tube rim. 17. Repeat steps 14–16 twice more for a total of 3 washes. 18. Resuspend the final washed cell pellet in 620 µL cold Sample Buffer from the BD Rhapsody™ Enhanced Cartridge Reagent V3 (catalog number 667052) and proceed to single cell capture with on-cartridge washing steps described below. See BD Rhapsody™ HT Single-Cell Analysis System Single-Cell Capture and cDNA Synthesis Protocol (Doc ID 23-24252) or BD Rhapsody™ HT Xpress System Single-Cell Capture and cDNA Synthesis Protocol (Doc ID 23-24253) for additional details. Note: Perform on-cartridge washing after cell settling (8-minute incubation) as follows: a) At the protocol section of "Loading cells in BD Rhapsody™ 8-Lane Cartridge", after cell load, incubate the cartridge in the dark at room temperature for 8 minutes. b) Place the cartridge on the BD Rhapsody™ HT Xpress and perform the following steps: _____________________________________________________________ Material to load        Volume (µL) 1 lane      Pipette Mode Air                     380                     Prime/Wash Cold Sample Buffer      380                     Prime/Wash Air                     380                     Prime/Wash Cold Sample Buffer      380                     Prime/Wash c) (Optional) Perform the scanner step: Cell Load Scan, if using BD Rhapsody™ HT Single-Cell Analysis System Single-Cell Capture and cDNA Synthesis Protocol (Doc ID 23-24252).
