New Kits on the Block:

Endothelial Transwell Permeability Assay Kit

Our partner Cell Biologics has developed a simple, reproducible, sensitive,

quantitative transwell permeability assay to measure endothelial

barrier function for wide analyses of multiple types of endothelial permeability in vitro. The assay will

be performed by a spectrometer-based absorbance reader (ELISA plate reader) at 450 nm within one

hour post endothelial treatment. The assay kit is suitable for primary endothelial cells and immortal cell

lines from multiple species.

The microvascular endothelial cell monolayer localized at the critical

interface between the blood and vessel wall has the vital functions of

regulating tissue fluid balance and supplying the essential nutrients

needed for the survival of the organism. The endothelial cells are able

to dynamically regulate its paracellular and transcellular pathways for

transport of plasma proteins, solutes, and liquid.

The endothelial barrier is a well-regulated structure, which maintains

a minimal and selective permeability to fluid and molecules under normal

physiological conditions. Vascular leakage is an important feature

in several diseases, such as septic shock, inflammation, disruption of

blood-brain barrier (BBB)-related neurological disorders, viral hemorrhagic fever, cancer and ischemiareperfusion

injuries. It is emergent to develop a highly sensitive and reliable assay to measure endothelial


ATAC-seq Kit

The ATAC-seq kit is a complete set of optimized reagents that are ideal to generate indexed DNA libraries

for ATAC-seq (Assay for Transposase-Accessible Chromatin using sequencing).

World's First Medium for Mouse (HSCs)

Hematopoietic Stem Cells for Maintaining

Undifferentiated State

HemEx-TypeA is a serum-free media, which contains Polyvinyl Alcohol

(PVA) and can be used for mouse Hematopoietic Stem Cells



Optimized for the

expansion of

mouse HSCs, Hematopoietic


and Progenitor

Cell (HSPCs) obtained

from bone


Can do expansion

culture of HSCs,

for more than 1

month in undifferentiated


PVA is used

instead of albumin.

In general, culture media for HSCs contains serum albumin. Such albumin

is required to induce cell division of HSCs. On theother

hand, albumin inhibits stable undifferentiated state.

Widely used purified or recombinant albumin contains small amount of

contaminants,but are tough to remove.

It is reported that such contaminants induce differentiation of HSCs.

Moreover, protein's oxidation reaction inducescellular senescence.

Thefore, albumin needs to be replaced by other chemicals.

Dr. Satoshi Yamazaki at The Institute of Medical Science, The University

of Tokyo reported that PVA can replace albumin (1).

Moreover, PVA is a stable chemical with no oxidation reaction in medium

so aging of HSCs are also suppressed. These advantages help to

do expansion culture of HSCs while maintaining undifferentiated state.


Please see the paper

of Nature, 571, 117 -

121 (2019).

Note : For culture,

addition of cytokine

is required.

Cells Proliferation Control Medium

Take the weekend off! 72hr change-free.

BOF-01 is a novel basal culture medium which can suppress proliferation

of human ES/iPS cells on feeder cell layers.

BOF-01 can be used by completely replacing the basal culture medium

(e.g. DMEM/F12) of the human ES/iPS cells.

Human ES/iPS cells can be maintained with BOF-01 for about 3days (up to 72

hours) without changing medium under normal culture conditions (37°C, 5%

CO2).After suppression of cell proliferation with BOF-01, cell growth can be

resumed by changing normal growth medium.

New Webinar

Take it personal! New Customized Media for

Animal & Human cell culture

You have your very specific cell culture needs

in your lab. Because you are unique and your

research is so too.In this webinar with CSO Dr.

Lothar Steeb, PELOBiotech, you´ll get an

overview of our services to customize your

academic or industrial research and production


Biomedical research is increasingly focusing

on genetic profiles, marker invention and other

patterns that characterise cells and processes.

More and more, gene analytical investigations

are moving into the focus of experiments. Exosomes,

miRNAs, smallRNAs and epigenetics

play an increasingly important role.

We contribute to this development by manufacturing special media

which are coordinated with the customer on a trial and cell basis.

We offer the customer every modification of classical media as well as

new chemically and thus serum-free media variations, which he

needs in order to exclude disturbing factors from the outset and thus

avoid false positive or false negative results.

Examples are RPMIs, DMEMs, SILAC BIT, chemically defined renal epithelial

cell media or all types of glucose-free media.

"I´zapft os"

Got the right answer?

Erich Kiesl caused the

biggest mishap so far

in the Octoberfest history:

In the eagerness

of the battle he forgot

1978 the obligatory

"Ozapft is!

The next time he

tapped, he managed

to confuse the vowels

and shouted loudly

"Izapft os!.

Some people swear

they have heard:

„O’batzt is!“
