pubmed:abstractText |
An increase in the level of intracellular free calcium concentration in rabbit and human neutrophils stimulated by chemotactic factors has been demonstrated directly using the calcium-sensitive fluorescent probe quin-2. Addition of f-Met-Leu-Phe (10(-9) M), C5a (3 x 10(-9) M) or leukotriene B4 (6 x 10(-8) M) to the neutrophils induces a rapid increase in the intracellular concentration of free calcium that reaches a maximum value 15 seconds following stimulation. At concentrations of f-Met-Leu-Phe less than 10(-8) M the enhancement is dose dependent with an ED50 of 8 x 10(-11) M and is significantly reduced in the presence of EGTA in the suspending medium.
