Product Specs

Introduction
Influenza B virus, a member of the Orthomyxoviridae family, exclusively infects humans and seals. Unlike Influenza A virus, its mutation is limited to genetic drift and reassortment. Influenza B virus evolves at a slower rate compared to Influenza A and a faster rate compared to Influenza C. While Influenza B virus mutates at a rate 2-3 times slower than type A, it still undergoes sufficient mutations to prevent long-lasting immunity. This enveloped virus has a virion structure consisting of a matrix protein, envelope, nucleoprotein complex, nucleocapsid, and polymerase complex. Its morphology can be either spherical or filamentous. The approximately 500 surface projections are composed of hemagglutinin and neuraminidase. The Influenza B virus genome comprises 14,648 nucleotides, organized into eight linear, negative-sense, single-stranded RNA segments. Each segment is enclosed within a separate nucleocapsid, all of which are surrounded by a single envelope.
Description
This product consists of allantoic fluid derived from 10-day-old embryonated eggs inoculated with the B/Qingdao/102/91 strain of Influenza B virus. The virus was purified using ultracentrifugation with a 10-40% sucrose gradient.
Inactivation
This product has been inactivated with Thimerosal and beta-propiolactone treatment. Standard microbiological/viral safe handling practices and techniques are required when working with this product.
Physical Appearance
A sterile-filtered, colorless solution.
Formulation
The B/Qingdao/102/91 solution is formulated with 0.1M NaCl, 10mM Tris HCl, 1mM EDTA (pH 8), 0.1% sodium azide (NaN3), and 0.005% thimerosal.
Stability

Product Science Overview

Introduction

Influenza B virus is a member of the Orthomyxoviridae family, which also includes Influenza A and C viruses. Unlike Influenza A, which infects a wide range of animals, Influenza B primarily infects humans and seals . The strain B/Qingdao/102/91 is a specific variant of the Influenza B virus.

Virus Structure and Genome

The Influenza B virus is an enveloped virus with a segmented, negative-sense, single-stranded RNA genome. The genome consists of eight segments, each encapsidated in a separate nucleocapsid and surrounded by an envelope . The virus has surface projections made of hemagglutinin (HA) and neuraminidase (NA), which are crucial for the virus’s ability to infect host cells .

Isolation and Purification

The B/Qingdao/102/91 strain was isolated from allantoic fluid of 10-day-old embryonated eggs inoculated with the virus. The virus was then purified using ultracentrifugation with a 10-40% sucrose gradient . This method ensures high purity, with the virus being greater than 90% pure as determined by SDS-PAGE .

Biological Characteristics

Influenza B virus mutates at a slower rate compared to Influenza A, but it still evolves enough to prevent lasting immunity . The virus’s limited host range means it does not undergo the same level of genetic drift and reassortment as Influenza A, which can infect birds and pigs .

Applications and Research

The B/Qingdao/102/91 strain is used in various research applications, including immunization protocols and antibody production . It is also used in serological studies to understand the immune response to Influenza B virus .

Storage and Stability

The purified virus is stored in a solution containing 0.1M NaCl, 10mM Tris HCl, 1mM EDTA (pH 8), 0.1% sodium azide (NaN3), and 0.005% thimerosal . For short-term storage, it is kept at 2-8°C, while long-term storage requires temperatures below -18°C to prevent freeze-thaw cycles .
