よくあるご質問（FAQ）

I read that carboxylate-modified latex (CML) beads have a "fluffy coat" of carboxyl groups on their surface. What is meant by this?

The CML beads have a high density of carboxyl groups at the surface. The surface layer is quite hydrophilic and at the appropriate pH (pH>5), are charged; due to electrostatic repulsion, this type of surface is 3-dimensional and may be considered analogous to the fuzz on a tennis ball.

I have some FluoSpheres polystyrene microspheres, with 20 nm diameter. They are aggregating a lot. What can I do about it?

The smaller the microspheres, the greater the propensity to aggregate. But the aggregation is not irreversible. Sonicate in a bath sonicator or vortex to disperse, just prior to use. You can also add a small concentration of Tween-20 or Triton X-100 (unless you are using them in a live-cell system).

I sonicated my 2.0 µm carboxylate-modified microspheres, as recommended, but saw foaming (bubbles) on top of the solution. Should I be concerned?

Use of a bath sonicator is recommended to help break up any aggregated microspheres. The foaming is from Tween-20, which is in the stock solution to help prevent aggregation. It is normal and expected to see bubbles from this. Do not use a probe sonicator, which would cause damage to the microspheres (as well as much more bubbling).

What is the warranty for FluoSpheres microspheres?

The warranty period for FluoSpheres microspheres is 1-year from the date of shipment.

After washing and centrifugation, there was only a very small pellet left of my microsphere beads and the solution was transparent. Why is this?

Centrifugation is not an effective way to collect smaller microspheres; many particles remain in the solution even if you can visualize a small pellet. For beads less than 1 µm in diameter, we recommend washing by either:

Cross-flow filtration, as these particles have a very high compression modulus and can withstand high g-forces without risk of harm or dialysis with a 500 kDa MWCO
Note: Microspheres greater than 1 µm in diameter can be centrifuged at 1,300 rpm.

Abstract
Fractal nature of regional ventilation distribution.
Authors:Altemeier WA, McKinney S, Glenny RW
Journal:J Appl Physiol
PubMed ID:10797111
'High-resolution measurements of pulmonary perfusion reveal substantial spatial heterogeneity that is fractally distributed. This observation led to the hypothesis that the vascular tree is the principal determinant of regional blood flow. Recent studies using aerosol deposition show similar ventilation heterogeneity that is closely correlated with perfusion. We hypothesize that ventilation ... More
Macelignan inhibits melanosome transfer mediated by protease-activated receptor-2 in keratinocytes.
Authors:Choi EJ, Kang YG, Kim J, Hwang JK,
Journal:Biol Pharm Bull
PubMed ID:21532167
'Skin pigmentation is the result of melanosome transfer from melanocytes to keratinocytes. Protease-activated receptor-2 (PAR-2) is a key mediator of melanosome transfer, which occurs as the melanocyte extends its dendrite toward surrounding keratinocytes that take up melanosomes by phagocytosis. We investigated the effects of macelignan isolated from Myristica fragrans HOUTT. ... More

Stresses at the cell-to-substrate interface during locomotion of fibroblasts.
Authors:Dembo M, Wang YL
Journal:Biophys J
PubMed ID:10096925
Recent technological improvements in the elastic substrate method make it possible to produce spatially resolved measurements of the tractions exerted by single motile cells. In this study we have applied these developments to produce maps of the tractions exerted by 3T3 fibroblasts during steady locomotion. The resulting images have a ... More
