Provider: Invitrogen Antibodies
Product name: CD56 (NCAM) Monoclonal Antibody (CMSSB), PerCP-eFluor™ 710, eBioscience™
Antibody type: Monoclonal
Antigen: Other
Description: Description: This CMSSB monoclonal antibody reacts with human CD56, also known as Neural Cell Adhesion Molecule (NCAM). CD56 is a highly glycosylated transmembrane molecule expressed by neurons and plays a role in the homotypic adhesion of neural cells. In the hematopoietic system, CD56 is expressed on NK cells and a subset of T cells referred to as NKT cells. Staining with CMSSB does not block binding of MEM188 or CB56.
Antibody clone number: CMSSB
Concentration: 5 µL/Test

Experimental details: Figure 6 Killing of hepatitis C virus subgenomic replicon cells requires interaction of innate immune cells. (A) Huh-7 Con1 cells were co-cultured with peripheral blood mononuclear cells (PBMCs), purified immune cells [natural killer (NK), plasmacytoid dendritic cells (pDC), or Monocytes (Mono)] or with a recombination of purified NK cells, pDCs and monocytes (NK + pDC + Mono) overnight. Supernatants were collected and measured for lactate dehydrogenase (LDH) activity ( n = 3). (B) Huh-7 Con1 cells were co-cultured with PBMCs, PBMCs depleted from NK cells (-NK), from pDCs (-pDC), from monocytes (-Mono), or from NK cells and pDCs (-NK -pDC) overnight. Supernatants were collected and measured for LDH activity ( n = 4). (C) Huh-7 cells were co-cultured with PBMCs overnight. NK cell (CD56 + , CD3 - ) expression of CD69, CD25, and TRAIL was analyzed by flow cytometry ( n = 4). (D-F) Huh-7 Con1 cells were co-cultured with PBMCs in the presence of an anti-TRAIL antibody or an IgG control antibody (each 10 ug/ml) overnight. LDH release was measured in the supernatant (D) , percentage of CFSE + monocytes (E) , and carboxyfluorescein succinimidyl ester (CFSE) mean fluorescence intensity (MFI) of monocytes (F) was determined ( n = 4).

Experimental details: Figure 1 Characterization of trophoblast-derived EVs (T-EVs). EVs were isolated from the villi according to a standard isolation procedure. A. Representative electron micrograph of T-EVs from patients with a normal pregnancy (NP), RSA patients who had an abnormal embryo karyotype (AK-RSA) and URSA patients. B.

After adsorption onto latex beads, T-EVs from NP, AK-RSA and URSA patients were analyzed by FCM with an anti-HLA-E PE-conjugated mAb (gray: isotype control; red: NP; green: AK-RSA; blue: URSA). F. The percentage of HLA-E + beads was statistically analyzed (n=25 in the NP group; n=13 in the AK-RSA patient group; n=12 in the URSA patient group). G. The expression of HLA-E in villus tissues from NP, AK-RSA and URSA patients was detected by an immunofluorescence assay. H. Human villus trophoblast cells, JEG-3 cells and HTR-8/Svneo cells were analyzed by FCM with an anti-HLA-E PE-conjugated mAb. Red: isotype control; blue: stained before permeabilization with IC fixation buffer (Invitrogen); green: stained after permeabilization with IC fixation buffer (Invitrogen). The data are representative of three independent experiments.

Experimental details: Figure 1 Cell preparation, morphology, expression of specific CD markers, and total amounts of cytokine-induced killer (CIK) cells. ( A ) Overview of the CIK cell preparation schedule. ( B ) CIK cells were observed under a microscope on day 3, 5, 10 and 14 after induction of peripheral blood mononuclear cells (PBMCs) (magnification, x250). ( C ) At day 14 after induction, the cell phenotype (CD3+CD56+) was identified by flow cytometry. The mean percentage of CD3+CD56+ cells from the six donors was about 32% +- 5%. ( D ) CIK cell numbers were measured using a cell counter (LUNA automated cell counter) at the indicated time points. After 14 days of cell culture, the total number of CIK cells expanded by more than 24-fold. Data from three independent experiments were used for statistical analysis and * p < 0.05.

Paired gRNA Screens Identify Cofactors of Neuronal Differentiation (A) Schematic representation of paired CRISPRa screens for neuronal-fate-determining TFs in human PSCs.
