Inside track

While HLA-B27 is by far the strongest and most well-known genetic marker linked with ankylosing spondylitis, several other genetic factors also contribute to disease susceptibility and can provide additional diagnostic or research insights. 1. HLA-B27 (primary marker) Present in ~90% of patients with AS of European ancestry. Not causative by itself — about 5–10% of

The human leukocyte antigen HLA-B27 is a variant of the class I major histocompatibility complex (MHC I) molecule. It is encoded by the HLA-B locus on chromosome 6 and expressed on almost all nucleated cells. Role in Health and Disease HLA-B27’s normal function is to present peptide antigens (derived from both self and non-self proteins)

Factor V’s role in coagulation Coagulation factor V is a key plasma glycoprotein in the blood-clotting cascade. In its activated form (Factor Va), it acts as a cofactor for Factor Xa, accelerating the conversion of prothrombin (Factor II) into thrombin. Thrombin then cleaves fibrinogen, resulting in fibrin formation — the fibrous mesh that gives structure to

No more waiting for the certificate to arrive by email — now you can download it anytime with just one click. We have introduced a new feature for instant generation of the CoA (Certificate of Analysis) for oligonucleotides directly in your customer account. What does the new feature allow?

Every year, on the second Thursday of November, the world observes World Quality Day – an opportunity to pause and recognize that quality is not a one-time goal. It is a mindset, a way of working, and a culture that permeates the entire organization. In the field of biotechnology, quality plays an absolutely fundamental role.

Warfarin is one of the most commonly prescribed oral anticoagulants worldwide. It is highly effective in preventing and treating thromboembolic disorders, but achieving the right dose is challenging — too low a dose may leave patients at risk of clot formation, while too high a dose can cause serious bleeding. One of the key reasons

A universal base is a modified nucleobase that can pair (non-selectively) with more than one of the standard DNA bases (A, T, G, C), ideally without significantly destabilizing the duplex or interfering with polymerase activity. Inosine is the most common universal base, although other possibilities exist: Common Universal Bases in Oligonucleotide Synthesis Name Description Base-Pairing

The degenerated base “N” and the universal base inosine (I) both serve to introduce base ambiguity in oligonucleotide synthesis, but they do so in different ways and are used in different contexts. Here’s a comparison: Inosine (I) vs. Degenerate Base “N” Feature Inosine (I) Degenerate Base “N” Chemical identity A real, single modified nucleotide A

Degen bases like dK and dP refer to synthetic, non-standard nucleobases used in molecular biology used in oligonucleotide synthesis — to allow degenerate (ambiguous) base pairing. They are alternatives to the classic “N” base, used to encode a mixture of A, T, G, C at a given position, but with greater control and performance in

Definition and Characteristics of Analog Bases Analog bases are chemically modified variants of the natural nucleotides—adenine (A), cytosine (C), guanine (G), and thymine (T)—that retain their ability to form complementary base pairs while exhibiting distinct chemical and structural properties. Within sequencing workflows, such modifications can minimize amplification bias, improve detection through enhanced fluorescent signaling, or

The IVDR regulation (EU 2017/746) fundamentally changes the rules in the field of in vitro diagnostics. While in the past, certain aspects of method validation could be approached in a more laboratory-driven and flexible way, it is now necessary to document every step clearly and link it to regulatory requirements.
