The density of luminous power, also called illumination. One lumen of luminous flux, uniformly incident on 1 square foot of area, produces an illuminance of 1 footcandle; in SI units, one lumen of luminous flux, uniformly incident on 1 square meter of area, produces an illuminance of 1 lux.

(2) (File Compare) An external DOS/Windows command that compares the content of two files. The following example compares the text files 1.TXT and 2.TXT. See file compare and Comp.
fc 1.txt 2.txt     blank areas
                     must match

  fc 1.txt 2.txt /w  blank areas do not
                     have to match

  fc 1.txt 2.txt /a  show only start and
                     end of mismatches

Text files are compared line by line, and discrepancies are displayed as follows:
***** first file
   ***** second file

Binary files, such as .EXE, .COM, .SYS, .OBJ, .LIB and .BIN, are compared byte for byte. To compare program files ABC.EXE and XYZ.EXE, type:
fc abc.exe xyz.exe

Binary file discrepancies are shown as follows. The AAAAAA is the hexadecimal location of the mismatched bytes, and the two BB's are the bytes (in hex) from the two files:

That's because chicken Fc fragments can't trigger the so-called complement cascade in humans -- the intense inflammatory reaction that underlies many of the more serious symptoms of serum sickness and anaphylaxis.
Virdante plans to pursue development of a second drug, a sialylated recombinant IgG Fc fragment ("sFc"), the segment of IgG responsible for the anti-inflammatory activity of IVIG.
In this study, we have fused the extracellular domain of CTLA-4 to the Fc fragment of the human IgG1 antibody.
4] Human genes: GALC, galactosylceramidase; ACADM, acyl-CoA dehydrogenase, C-4 to C-12 straight chain; ACADVL, acyl-CoA dehydrogenase, very long chain; GALT, galactose-1-phosphate uridyl transferase; PAH, phenylalanine hydroxylase; FCGR2A, Fc fragment of IgG, low affinity IIa, receptor (CD32); RPP30, ribonuclease P/MRP 30kDa subunit.
Ravetch has further shown that these anti-inflammatory properties can be reproduced with a fully recombinant preparation of appropriately sialylated IgG Fc fragments (sFc), providing a more efficacious and potent treatment at lower dose levels.
Because rhP/Fc is conjugated with an Fc fragment of IgG, to evaluate the concentrations of rhP/Fc, we used a colorimetric Fc quantification assay set generally used to estimate IgG concentration in serum.
4] Human genes: IGHG1 human IgG1 heavy chain constant region; IGHG4 human IgG4 heavy chain constant region; and IGHE, human IgE heavy chain constant region; FCERIA, Fc fragment of IgE, high affinity I, receptor for; alpha polypepfide; FCER1G, Fc fragment of IgE, high affinity I, receptor for; gamma polypepfide; MS4A2, membrane-spanning 4-domains, subfamily A, member 2 (Fc fragment of IgE, high affinity I, receptor for beta polypeptide).
2] fragment, whereas the remaining 331 samples contained heterophilic antibodies directed against the murine Fc fragment.
Humanization of animal antibodies (15) and modification of assay antibodies by removal of the Fc fragment (16) are well-known methods that often dramatically reduce interference.
Initial studies showed that this interference mostly could be solved by the removal of the Fc fragment from the capture antibody, an indication of the presence of heterophilic antibodies.
Digoxin-specific Fab fragments are produced by cleaving sheep digoxin-specific IgG with papain to form two Fab fragments (50 000 Da each) and one 50 000-Da Fc fragment (2).
