CRBCs 2.0 mL

Chicken Red Blood Cells

Ideal for initial standardization and monitoring of the cytometer's optical and fluorescence parameters and PMT stability. Makes peak assessment a snap.

2.0 mL Catalog No. 1004$108.00

BioSure^® Chicken Red Blood Cell (CRBCs) cytometry control is a red cell standard for use in calibration and set-up of flow cytometers (FACS, EPICS). CRBCs are prepared from chicken erythrocytes that have been processed to remove leukocytes and are fixed with glutaraldehyde. CRBCs are a useful cytometry control because these processed but unstained cells fluoresce at about the intensity as cells stained for immunofluorescence.

FORM

BioSure^® CRBCs are supplied in 2.0 mL (P/N 1004) or 6.0 mL (P/N 1005) volumes. The cell count per milliliter is at least 2.5 X (10)⁷ CRBCs. The control is guaranteed to have a CV of less than or equal to 10% on FL2.

STABILITY

CRBCs are stable at 2^o - 8^o C until the expiration date denoted on each vial label. Freshly diluted (1:10) preparations are stable for at least 72 hours at room temperature (25^o - 30^o C), although longer stability has been observed when diluted material is stored at 2^o - 8^o C.

PREPARATION OF WORKING SOLUTION

The recommended working solution is a 1:10 dilution of the stock solution in particulate-free physiological saline or isotonic buffered saline. This provides an adequate cell density and sufficient working solution for several days.

1. Gently mix the stock CRBCs, and add 2 drops into a test tube (13 X 75 mm).

2. Add 0.9 mL of diluent, mix and evaluate.

Typical CRBC Graph

NOTE: The flow cell of some cytometers is susceptible to clogging. Filtering the stained preparation through a 30 - 50 mesh nylon screen will eliminate large nuclear aggregates.
