Analysis of Cardiac Troponin I (cTnI) in human embryonic stem cell (hESC)-derived cardiomyocytes. hESC-derived cardiomyocytes (Evans lab, UCSD) were disassociated and fixed in BD Cytofix™ Fixation Buffer (Cat. No. 554655), permeabilized with BD Phosflow™ Perm/Wash Buffer I (Cat. No. 557885) and stained with PE Mouse Anti-Myosin Heavy Chain (Cat. No. 564408) and Alexa Fluor® 647 Mouse Anti-Cardiac Troponin I. The cells were first gated on light scatter properties and then analyzed for Myosin Heavy Chain and cTnI expression. Flow cytometry was performed on a BD LSRFortessa™ Cell Analyzer System.

Preparation And Storage
Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated to Alexa Fluor® 647 under optimum conditions, and unreacted Alexa Fluor® 647 was removed.
Product Notices
- This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
- An isotype control should be used at the same concentration as the antibody of interest.
- Alexa Fluor® is a registered trademark of Molecular Probes, Inc., Eugene, OR.
- Alexa Fluor® 647 fluorochrome emission is collected at the same instrument settings as for allophycocyanin (APC).
- The Alexa Fluor®, Pacific Blue™, and Cascade Blue® dye antibody conjugates in this product are sold under license from Molecular Probes, Inc. for research use only, excluding use in combination with microarrays, or as analyte specific reagents. The Alexa Fluor® dyes (except for Alexa Fluor® 430), Pacific Blue™ dye, and Cascade Blue® dye are covered by pending and issued patents.
- Source of all serum proteins is from USDA inspected abattoirs located in the United States.
- Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.

Antibody Details
C5
The C5 monoclonal antibody specifically binds to Cardiac Troponin I (cTnI). cTnI is a ~30-kDa protein that is also known as TNNI3 and TNNC1. Troponin I is the inhibitory subunit of Troponin, which also contains the subunits Troponin C and Troponin T. Troponin aids the Ca[2+]-dependent interaction of actin and myosin, which are the main contracile components in muscle cells. cTnI is specifically expressed in cardiac tissue, while skeletal troponin I is expressed in skeletal muscle in slow and fast isoforms. Hereditary cardiomyopathy is associated with mutations in cTnI. During product development, the purified C5 monoclonal antibody detected cTnI by western blot analysis of cellular lysates and flow cytometric analysis of fixed and permeabilized cells.

Format Details
Alexa Fluor™ 647
Alexa Fluor™ 647 Dye is part of the BD red family of dyes. This is a small organic fluorochrome with an excitation maximum (Ex Max) at 653-nm and an emission maximum (Em Max) at 669-nm. Alexa Fluor 647 is designed to be excited by the Red laser (627-640 nm) and detected using an optical filter centered near 520-nm (e.g., a 660/20 nm bandpass filter). Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
