Apc conjugated c kit

Manufactured by Thermo Fisher Scientific

The APC-conjugated c-kit is a fluorescently labeled antibody that binds to the c-kit receptor, also known as CD117. C-kit is a tyrosine kinase receptor expressed on the surface of various cell types, including hematopoietic stem cells, mast cells, and certain cancer cells. The APC (Allophycocyanin) fluorescent dye is conjugated to the c-kit antibody, enabling the detection and identification of c-kit positive cells using flow cytometry or other fluorescence-based techniques.

Primary hematopoietic stem cells were isolated from the bone marrow of female C57BL/6 mice (Jackson Labs; Ages 1–3 months) as described previously [34 (link)]. All animal experiments were conducted with permission obtained from the University of Illinois Institutional Animal Care and Use Committee (IACUC), Protocols #12–033, 14–1580. Lineage negative marrow was enriched using the EasySep Mouse Hematopoietic Progenitor Cell Enrichment kit (StemCell Technologies, Vancouver, Canada). HSCs were subsequently isolated via FACS as the Lin Sca-1+ c-kit+ (LSK) sub-fraction using a cocktail of antibodies (eBioscience, San Diego, CA): PE-conjugated Sca-1 (1:100 dilution), APC-conjugated c-kit (1:100 dilution), and a 1:100 dilution of an FITC-conjugated Lineage (Lin) cocktail (CD5, B220, Mac-1, CD8a, Gr-1, Ter-119). LSK cells were sorted using a BD FACS Aria II flow cytometer (BD FACS Diva software).

Isolation and Purification of Hematopoietic Stem and Progenitor Cells

For isolating HSPCs from bone marrow, magnetic‐activated cell sorting (MACS), and fluorescence‐activated cell‐sorting (FACS) analysis were performed as follow. Bone marrow cells were harvested from donor femur and tibia by crushing bones with mortar and pestle in PBS containing 2% FCS and filtering through a 40 μm mesh filter. After red blood cells were lysed, bone marrow cells were incubated with a cocktail of biotin‐conjugated lineage‐specific antibodies against CD45, Gr1, CD11b, Ter119, CD4, CD8, CD3 (553,029, 553,060, 553,086, 553,125, 553,309, 553,672, and 553,728, respectively, BD Biosciences), and anti‐Biotin microbeads for MACS (130–090‐485, Miltenyi Biotec). The separation of lineage‐negative cells was performed with an autoMACS pro separator (Miltenyi Biotec). Lineage‐depleted cells stained with APC‐conjugated c‐Kit (17–1171‐81, eBioscience) and PECy7‐conjugated Sca‐1 (108,116, Biolegend) antibodies were sorted using FACS Aria II (BD Biosciences) with over 95% purity. The DsRed fluorescence expression in the purified HSPCs was over 99% by FACS DiVa software (BD Biosciences).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
